Announcing EzAnimation

Flutter offers stunning simplicity in aspects like building UI and the overall process of app development. Some sorts of animations such as implicit animations are also very easy to use and do not require any knowledge of animating objects. However, building explicit animations in the normal way is a concern I have often heard and I decided to do something about it.

The Current Situation

Let’s first look at a normal Flutter animation that animates a square from size 0 to 100.0 to establish the problem:

class _MyHomePageState extends State<MyHomePage> with SingleTickerProviderStateMixin {
  AnimationController _controller;
  Animation animation;

  @override
  void initState() {
    super.initState();
    _controller = AnimationController(vsync: this, duration: Duration(seconds: 1));
    animation = Tween(begin: 0.0, end: 100.0).animate(_controller);

    _controller.forward();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: AnimatedBuilder(
          animation: animation,
          builder: (context, snapshot) {
            return Container(
              color: Colors.blue,
              width: animation.value,
              height: animation.value,
            );
          },
        ),
      ),
    );
  }
}

Creating an explicit animation has cognitive overhead because many things are required to work together. Developers have questions and feedback such as:

  1. What is the SingleTickerProviderStateMixin?
  2. Why are controllers and animations separate?
  3. Creating a Curved animation is hard
  4. Creating a sequence is not straightforward

Introducing EzAnimation

Here’s the most basic possible animation using EzAnimation doing the same thing above:

Define

var animation = EzAnimation(0.0, 100.0, Duration(seconds: 1));

Start:

animation.start();

Observe:

AnimatedBuilder(
  animation: animation,
  builder: (context, snapshot) {
    return Container(
      color: Colors.blue,
      width: animation.value,
      height: animation.value,
    );
  },
),

No Ticker is required here, no AnimationController is required here, no Tween is required here, and it is very easy to supply a curve to the animation as will be shown later. (Note that this is not the most efficient type of animation, more details on that later.)

The complete code for this equivalent to the one shown in the first section is:

class _MyHomePageState extends State<MyHomePage> {
  var animation = EzAnimation(0.0, 100.0, Duration(seconds: 1));

  @override
  void initState() {
    super.initState();
    animation.start();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: AnimatedBuilder(
          animation: animation,
          builder: (context, snapshot) {
            return Container(
              color: Colors.blue,
              width: animation.value,
              height: animation.value,
            );
          },
        ),
      ),
    );
  }
}

When multiple animations are involved, this is much easier to handle than to use multiple controllers, animations and Tweens.

Announcing your Ioniconf Speakers

When we announced Ioniconf a few weeks ago, we were thrilled to see the response and sign-ups from all of our community members. I mean, we didn’t even say who was speaking at the event, so thanks for being so enthusiastic! But now we’re ready to share who is speaking at Ioniconf…so without further ado…here are your speakers!

We’ve brought together speakers from various different technology backgrounds and experiences to share insights not only on Ionic, but the Web Platform as a whole. The range of topics include, the latest in testing and static hosting, how to ship a product, and so much more. Not only do the Ioniconf speakers represent a broad cross-section of the tech landscape, they also bring a diverse set of viewpoints and perspectives. We’re thrilled that they’ve all agreed to present at Ioniconf and we hope that you are excited to learn from them as well.

We’ll be using Twitter to gather questions during the conference, so as talks are going on, use the hashtag #askioniconf to ask your questions.

I wanted to take a moment and highlight a few speakers whose talks I think will really stand out during the conference.

Announcing Web Previews in Appflow

Today, we’re thrilled to announce Web Previews in Appflow, the easiest way to share what you’re working on with coworkers, stakeholders, and more.

Unfamiliar with Appflow? It’s a mobile DevOps solution by Ionic that makes it easy to continuously build, deploy, and update mobile app experiences across iOS, Android, and the web. With Appflow, you can fully automate your team’s app development workflow, and go from idea to production in less time.

New to Ionic or Appflow? Try our step-by-step app wizard to build your first app and generate a web preview in minutes.

Web Previews represent the next step in our belief in the web first development strategy, and we’re especially excited for what this feature enables for teams who want a quick and easy way to share pre-production versions of their app, without the overhead and complexity of managing TestFlight, iOS enterprise certs, or any of the more complicated methods of showing off what you’ve built.

Web Previews: Faster feedback loops

Much of the app development process, especially for mobile apps, involves getting the design just right along with fine tuning the overall user experience. To do so effectively, you have to get the app into your user’s hands – screenshots and mockups don’t cut it.

Traditionally, developers would accomplish this via testing and sharing apps like TestFlight, or by generating native app binaries and distributing them via iOS enterprise certs. When it comes to iterating quickly, such as tweaking a design change or fixing bugs, it’s annoying to get slowed down by native builds.

Fortunately, when you combine Ionic Framework’s UI components and Capacitor’s cross-platform APIs, you can develop and test 99% of your app in the browser. Also known as the web first approach, you create the app locally then deploy to mobile devices and app stores when ready.

Today, we’re taking that a step further – sharing your app with your team is now a URL click away:

Announcing Identity Vault 4.0

Today I’m excited to announce Ionic Identity Vault 4.0, the latest release from our suite of pre-built mobile solutions. Identity Vault makes it easy to add secure biometric authentication to your Ionic apps in minutes, using the latest in native security best practices.

This latest release of Identity Vault offers enhanced Android support by adding Android 10 (SDK 29) and AndroidX support. With this addition, Face Unlock and Iris Unlock are now available.
