Animations Users Love

This is an introduction to rive(formerly flare) animations for your flutter application. Why should you use rive?

First, the Adobe After Effects animation files can be loaded and converted by rive studio which also means that the Lottie files site files can also be loaded and converted into riv format by the-rive studio web app. The gist is that it allows you to reduce the number of animation controllers you have write-by-hand.

First, before we get to flutter code on how to use the rive plugin let’s cover some basics about rive. You need the animation-name for your animation controller to use. That name can be found in the web player preview of any animation within the rive web app at:

https://rive.app/preview/?filename=224-424-luke-vs-darth

That is the animation by Bobbeh which I am using in this flutter demo; as you notice the right panel shows the animation-name as Animation 1(the artboard) which will get used in our animation controller.

To install the rive plugin in your pubspec under dependencies:

rive: ^0.7.9

How To Create User-Generated Content? [A Simple Guide To Grow Your Brand]

In this digital world, online businesses aspire to catch the attention of users in a modern and smarter way. To achieve it, they need to traverse through new approaches. Here comes to spotlight is the user-generated content or UGC.

What is user-generated content?
“ It is the content by users for users.”

Generally, the UGC is the unbiased content created and published by the brand users, social media followers, fans, and influencers that highlight their experiences with the products or services. User-generated content has superseded other marketing trends and fallen into the advertising feeds of brands. Today, more than 86 percent of companies use user-generated content as part of their marketing strategy.

In this article, we have explained the ten best ideas to create wonderful user-generated content for your brand. Let’s start without any further ado.

1. Content From Social Media Platforms
   In the year 2020, there are 3.81 million people actively using social media around the globe. That is the reason social media content matters. Whenever users look at the content on social media that is posted by an individual, then they may be influenced by their content. Perhaps, it can be used to gain more customers or followers on your social media platforms.

Generally, social media platforms help the brand to generate content for your users. Any user content that promotes your brand on the social media platform is the user-generated content for your business. When users create and share content on social media, they get 28% higher engagement than a standard company post.

Furthermore, you can embed your social media feed on your website also. you can use the Social Stream Designer WordPress plugin that will integrate various social media feeds from different social media platforms like Facebook, Twitter, Instagram, and many more. With this plugin, you can create a responsive wall on your WordPress website or blog in a few minutes. In addition to this, the plugin also provides more than 40 customization options to make your social stream feeds more attractive.

2. Consumer Survey
   The customer survey provides powerful insights you need to make a better decision for your business. Moreover, it is great user-generated content that is useful for identifying unhappy consumers and those who like your product or service.

In general, surveys can be used to figure out attitudes, reactions, to evaluate customer satisfaction, estimate their opinions about different problems. Another benefit of customer surveys is that collecting outcomes can be quick. Within a few minutes, you can design and load a customer feedback survey and send it to your customers for their response. From the customer survey data, you can find your strengths, weaknesses, and get the right way to improve them to gain more customers.

3. Run Contests
   A contest is a wonderful way to increase awareness about a product or service. Contest not just helps you to enhance the volume of user-generated content submissions, but they also help increase their quality. However, when you create a contest, it is important to keep things as simple as possible.

Additionally, it is the best way to convert your brand leads to valuable customers. The key to running a successful contest is to make sure that the reward is fair enough to motivate your participation. If the product is relevant to your participant, then chances are they were looking for it in the first place, and giving it to them for free just made you move forward ahead of your competitors. They will most likely purchase more if your product or service satisfies them.

Furthermore, running contests also improve the customer-brand relationship and allows more people to participate in it. It will drive a real result for your online business. If your WordPress website has Google Analytics, then track contest page visits, referral traffic, other website traffic, and many more.

4. Review And Testimonials
   Customer reviews are a popular user-generated content strategy. One research found that around 68% of customers must see at least four reviews before trusting a brand. And, approximately 40 percent of consumers will stop using a business after they read negative reviews.

The business reviews help your consumers to make a buying decision without any hurdle. While you may decide to remove all the negative reviews about your business, those are still valuable user-generated content that provides honest opinions from real users. Customer feedback can help you with what needs to be improved with your products or services. This thing is not only beneficial to the next customer but your business as a whole.

Reviews are powerful as the platform they are built upon. That is the reason it is important to gather reviews from third-party review websites like Google review, Facebook review, and many more, or direct reviews on a website. It is the most vital form of feedback that can help brands grow globally and motivate audience interactions.

However, you can also invite your customers to share their unique or successful testimonials. It is a great way to display your products while inspiring others to purchase from your website.

5. Video Content
   A great video is a video that is enjoyed by visitors. These different types of videos, such as 360-degree product videos, product demo videos, animated videos, and corporate videos. The Facebook study has demonstrated that users spend 3x more time watching live videos than normal videos. With the live video, you can get more user-created content.

Moreover, Instagram videos create around 3x more comments rather than Instagram photo posts. Instagram videos generally include short videos posted by real customers on Instagram with the tag of a particular brand. Brands can repost the stories as user-generated content to engage more audiences and create valid promotions on social media.

Similarly, imagine you are browsing a YouTube channel, and you look at a brand being supported by some authentic customers through a small video. So, it will catch your attention. With the videos, they can tell you about the branded products, especially the unboxing videos displaying all the inside products and how well it works for them. That type of video is enough to create a sense of desire in the consumers.

Add beautiful animated effects & builders in Flutter via API

Flutter Animate

A performant library that makes it simple to add almost any kind of animated effect in Flutter.

1. Pre-built effects, like fade, scale, slide, flip, blur, shake, shimmer, shadows, crossfades, and color effects (saturation, color, and tint)
2. Easy custom effects and simplified animated builders
3. Synchronize animations to scroll, notifiers, or anything
4. Integrated events

All via a simple, unified API without fussing with AnimationController and StatefulWidget.

Above: The included example app.

Duration extensions

Extension methods for num, to make specifying durations easier. For example: 2.seconds, 0.1.minutes, or 300.ms.

AnimatedController extensions

A loop extension method for AnimatedController which is identical to repeat, but adds a count parameter to specifiy how many times to play.

Basics

Syntax

To apply effects, wrap the target widget in Animate, and specify a list of effects:

Animate(
  effects: [FadeEffect(), ScaleEffect()],
  child: Text("Hello World!"),
)

It also adds an .animate() extension method to all widgets, which wraps the widget in Animate(). Each effect also adds a chainable extension method to Animate to enable a shorthand syntax:

Text("Hello World!").animate().fade().scale()

NOTE: The shortform style is used in this README, but all functionality is available in either format.

Delay, duration, curve

Effects have optional delay, duration, and curve parameters. Effects run in parallel, but you can use a delay to run them sequentially:

Text("Hello").animate()
  .fade(duration: 500.ms)
  .scale(delay: 500.ms) // runs after fade.

Note that effects are "active" for the duration of the full animation, so for example, two fade effects on the same target can have unexpected results (SwapEffect detailed below, can help address this).

If not specified (or null), these values are inherited from the previous effect, or from Animate.defaultDuration and Animate.defaultCurve if it is the first effect:

Text("Hello World!").animate()
  .fadeIn() // uses `Animate.defaultDuration`
  .scale() // inherits duration from fadeIn
  .move(delay: 300.ms, duration: 600.ms) // runs after the above w/new duration
  .blurXY() // inherits the delay & duration from move

Animate has its own delay parameter, which defines a delay before the animation begins playing. Unlike the delay on an Effect, it is only applied once if the animation repeats.

Text("Hello").animate(
    delay: 1000.ms, // this delay only happens once at the very start
    onPlay: (controller) => controller.repeat(), // loop
  ).fadeIn(delay: 500.ms) // this delay happens at the start of each loop

Other Effect Parameters

Most effects include begin and end parameters, which specify the start/end values. These are usually "smart" in the sense that if only one is specified then the other will default to a "neutral" value (ie. no visual effect). If both are unspecified the effect should use visually pleasing defaults.

// an opacity of 1 is "neutral"
Text("Hello").animate().fade() // begin=0, end=1
Text("Hello").animate().fade(begin: 0.5) // end=1
Text("Hello").animate().fade(end: 0.5) // begin=1

Many effects have additional parameters that influence their behavior. These should also use pleasant defaults if unspecified.

Text('Hello').animate().tint(color: Colors.purple)

Sequencing with ThenEffect

ThenEffect is a special convenience "effect" that makes it easier to sequence effects. It does this by establishing a new baseline time equal to the previous effect's end time and its own optional delay. All subsequent effect delays are relative to this new baseline.

In the following example, the slide would run 200ms after the fade ended.

Text("Hello").animate()
  .fadeIn(duration: 600.ms)
  .then(delay: 200.ms) // baseline=800ms
  .slide()

Animating lists

The AnimateList class offers similar functionality for lists of widgets, with the option to offset each child's animation by a specified interval:

Column(children: AnimateList(
  interval: 400.ms,
  effects: [FadeEffect(duration: 300.ms)],
  children: [Text("Hello"), Text("World"),  Text("Goodbye")],
))

// or shorthand:
Column(
  children: [Text("Hello"), Text("World"),  Text("Goodbye")]
    .animate(interval: 400.ms).fade(duration: 300.ms),
)

Shared effects

Because Effect instances are immutable, they can be reused. This makes it easy to create a global collection of effects that are used throughout your app and updated in one place. This is also useful for design systems.

MyGlobalEffects.transitionIn = <Effect>[
  FadeEffect(duration: 100.ms, curve: Curves.easeOut),
  ScaleEffect(begin: 0.8, curve: Curves.easeIn)
]

// then:
Text('Hello').animate(effects: MyGlobalEffects.transitionIn)

Custom effects & builders

It is easy to write new resuable effects by extending Effect, but you can also easily create one-off custom effects by using CustomEffect, ToggleEffect, and SwapEffect.

CustomEffect

CustomEffect lets you build custom animated effects. Simply specify a builder function that accepts a context, value, and child. The child is the target of the animation (which may already have been wrapped in other effects).

For example, this would add a background behind the text and fade it from red to blue:

Text("Hello World").animate().custom(
  duration: 300.ms,
  builder: (context, value, child) => Container(
    color: Color.lerp(Colors.red, Colors.blue, value),
    padding: EdgeInsets.all(8),
    child: child, // child is the Text widget being animated
  )
)

By default it provides a value from 0-1 (though some curves can generate values outside this range), based on the current time, duration, and curve. You can also specify begin and end values as demonstrated in the example below.

Animate can be created without a child, so you use CustomEffect as a simplified builder. For example, this would build text counting down from 10, and fading out:

Animate().custom(
  duration: 10.seconds,
  begin: 10,
  end: 0,
  builder: (_, value, __) => Text(value.round()),
).fadeOut()

ToggleEffect

ToggleEffect also provides builder functionality, but instead of a double, it provides a boolean value equal to true before the end of the effect and false after (ie. after its duration).

Animate().toggle(
  duration: 2.seconds,
  builder: (_, value, __) => Text(value ? "Before" : "After"),
)

This can also be used to activate "Animated" widgets, like AnimatedContainer, by toggling their values with a minimal delay:

Animate().toggle(
  duration: 1.ms,
  builder: (_, value, __) => AnimatedContainer(
    duration: 1.seconds,
    color: value ? Colors.red : Colors.green,
  ),
)

SwapEffect

SwapEffect lets you swap out the whole target widget at a specified time:

Text("Before").animate()
  .swap(duration: 900.ms, builder: (_, __) => Text("After"))

This can also be useful for creating sequential effects, by swapping the target widget back in, effectively wiping all previous effects:

text.animate().fadeOut(300.ms) // fade out & then...
  // swap in original widget & fade back in via a new Animate:
  .swap(builder: (_, child) => child.animate().fadeIn())

Events & callbacks

Animate includes the following callbacks:

• onInit: the internal AnimationController has been initialized
• onPlay: the animation has started playing after any Animate.delay
• onComplete: the animation has finished

These callbacks return the AnimationController, which can be used to manipulate the animation (ex. repeat, reverse, etc).

Text("Horrible Pulsing Text")
  .animate(onPlay: (controller) => controller.repeat(reverse: true))
  .fadeOut(curve: Curves.easeInOut)

For more nuanced callbacks, use CallbackEffect or ListenEffect.

CallbackEffect

CallbackEffect lets you add a callback to an arbitrary postion in your animations. For example, adding a callback halfway through a fade:

Text("Hello").animate().fadeIn(duration: 600.ms)
  .callback(duration: 300.ms, callback: (_) => print('halfway'))

As with other effects, it will inherit the delay and duration of prior effects:

Text("Hello").animate().scale(delay: 200.ms, duration: 400.ms)
  .callback(callback: (_) => print('scale is done'))

ListenEffect

ListenEffect lets you register a callback to receive the animation value (as a double) for a given delay, duration, curve, begin, and end.

Text("Hello").animate().fadeIn(curve: Curves.easeOutExpo)
  .listen(callback: (value) => print('current opacity: $value'))

The above example works, because the listen effect inherits duration and curve from the fade, and both use begin=0, end=1 by default.

Adapters and Controllers

By default, all animations are driven by an internal AnimationController, and update based on elapsed time. For more control, you can specify your own external controller, or use an adapter. You can also set autoPlay=false if you want to start the animation manually.

Adapters synchronize the AnimationController to an external source. For example, the ScrollAdapter updates an animation based on a ScrollController so you can run complex animations based on scroll interactions.

You still define animations using durations, but the external source must provide a 0-1 value.

Flutter Animate ships with a collection of useful adapters. Check them out for more information.

Reacting to State Changes

Animate can react to state changes similar to "Animated" widgets (ex. AnimatedOpacity). Simply set up your animation normally, but set a target value. When the value of target changes, it will automatically animate to the new target position (where 0 is the beginning and 1 is the end).

For example, combined with logic that toggles _over via setState, this will fade and scale the button on roll over:

MyButton().animate(target: _over ? 1 : 0)
  .fade(end: 0.8).scaleXY(end: 1.1)

Testing Animations

When testing animations, you can set Animate.restartOnHotReload=true which will cause all animations to automatically restart every time you hot reload your app.

Installation

Grab it from pub.dev.

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add flutter_animate

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  flutter_animate: ^4.1.1+1

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:flutter_animate/flutter_animate.dart';

example/lib/main.dart

import 'package:example/examples/everything_view.dart';
import 'package:flutter/material.dart';

import 'examples/adapter_view.dart';

    return const MaterialApp(
      title: 'Flutter Animate Demo',
      debugShowCheckedModeBanner: false,
      home: FlutterAnimateExample(),
    );
  }
}

// this is a very quick and dirty example.
class FlutterAnimateExample extends StatefulWidget {
  const FlutterAnimateExample({Key? key}) : super(key: key);

Python Animations With Matplotlib

Make the most of your simulations by knowing how to animate graphs.

In Python, plotting graphs is straightforward — you can use powerful libraries like Matplotlib. But when you are running simulations, basic plots may not always be enough. You may want to show an animation that helps you understand how the state changes over time.

Luckily, it’s just as easy to create animations as it is to create plots with Matplotlib.

In this guide, you are going to learn:

• How to create a basic Matplotlib plot.
• How to create a basic animated plot using Matplotlib.
• How to create a live-updating graph of a stock price.

Matplotlib

Matplotlib is a commonly used visualization library in Python. You can plot interactive graphs, histograms, bar charts, and so on.
