Share Files and Screenshot Widgets Flutter

share_files_and_screenshot_widgets

This pub lets you share any kind of files (csv, mp4, png etc), take screenshot of the widgets you want and return as Image and share them directly as well in the form of an image.

Usage

Example

To use this package :

  • add the dependency to your [pubspec.yaml] file.
  dependencies:
    flutter:
      sdk: flutter
    share_files_and_screenshot_widgets:

How to use

Take ScreenShot of Widgets

//define
GlobalKey previewContainer = new GlobalKey();

//wrap your widget with
RepaintBoundary(
  key: previewContainer,
  child: YourWidget()
),

//call this function for taking screenshot
ShareFilesAndScreenshotWidgets()
    .takeScreenshot(previewContainer, originalSize)
    .then((Image value) {
  setState(() {
    _image = value;
  });
});

Directly Share ScreenShot of Widgets

//define
GlobalKey previewContainer = new GlobalKey();

//wrap your widget with
RepaintBoundary(
  key: previewContainer,
  child: YourWidget()
),

//call this function for sharing screenshot
ShareFilesAndScreenshotWidgets().shareScreenshot(
  previewContainer,
  originalSize,
  "Title",
  "Name.png",
  "image/png",
  text: "This is the caption!");

Share Any Type of File

ByteData bytes =
    await rootBundle.load('assets/example.jpg');
Uint8List list = bytes.buffer.asUint8List();
ShareFilesAndScreenshotWidgets().shareFile(
    "Title", "Name.jpg", list, "image/jpg",
    text: "This is the caption!");
ByteData bytes =
    await rootBundle.load('assets/example.mp4');
Uint8List list = bytes.buffer.asUint8List();
ShareFilesAndScreenshotWidgets().shareFile(
    "Title", "Name.mp4", list, "video/mp4",
    text: "This is the caption!");
ByteData bytes =
    await rootBundle.load('assets/example.mp3');
Uint8List list = bytes.buffer.asUint8List();
ShareFilesAndScreenshotWidgets().shareFile(
    "Title", "Name.mp3", list, "audio/mp3",
    text: "This is the caption!");

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add share_files_and_screenshot_widgets

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

dependencies:
  share_files_and_screenshot_widgets: ^1.0.6

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

Import it

Now in your Dart code, you can use:

import 'package:share_files_and_screenshot_widgets/share_files_and_screenshot_widgets.dart'; 

example/lib/main.dart

import 'dart:typed_data';
import 'package:flutter/material.dart';

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

sksl_warm-up

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

flutter_autofill

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSliderDatePicker with support for date range and time picker with the new style.

flutter_DatePicker

New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

You can get more free Flutter tutorials you can follow these courses:

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).

flutter-mobile-desktop-web-embedded_min

Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.

humming_bird_dart_flutter

Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

Exploring Flutter Widgets || Flutter Container Widget & Its Properties #15

In this video I have discussed about Container widget and its different properties.

It is a widget which is used to hold the child widget with the ability to apply some styling properties.
Key points

  1. If the container widget does not have a child it will fill up the the given area on screen.

  2. If it contains child it will have the same width and height as of its child.

  3. It should not be rendered directly on screen without parent widget. We can use Center widget, Padding Widget, Column Widget, Row Widget or Scaffold Widget as parent.
