A complete Picture-In-Picture mode plugin for android API level 26+ (Android Oreo).

Big shout out to the original author of this library @puntitOwO, who created this library.

Provides methods to check feature availability, enter PIP mode, callbacks for mode change and PIP Actions support.

Reasoning behind forking this library

We have forked the library, becuase we could see that the library hasn't been actively worked on in two years time.

In this version of the library, we shall incorporate changes that ensure future-facing compatibility and also allow extensions that could enable the library to cover more use-cases.

Features

• Verify PIP system availability and current state.
• Method to enter PIP mode, with aspect ratio, auto enter and seamless resize parameters.
• On PIP mode change Callbacks.
• Widget to build PIP-dependent layouts.
• PIP Actions (media action presets).

Installation

In the dependencies: section of your pubspec.yaml, add the following line:

  simple_pip_mode: <latest_version>

Usage

This section has example code for the following tasks:

• Update manifest
• Verify PIP support
• Entering PIP mode
• Enabling callbacks
• Using callbacks
• Using the PIP Widget
• Using PIP Actions

Update manifest

Add android:supportsPictureInPicture="true" to the activity on your AndroidManifest.xml.

Verify pip support

Use SimplePip.isPipAvailable and SimplePip.isPipActivated static getters to verify whether the device supports Picture In Picture feature and the feature is currently activated respectively.

Entering pip mode

Import simple_pip.dart file and call enterPipMode method.

import 'package:simple_pip_mode/simple_pip.dart';

class MyWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return IconButton(
      icon: Icon(Icons.picture_in_picture),
      onPressed: () => SimplePip().enterPipMode(),
    );
  }
}

Setting automatic pip mode

Import simple_pip.dart file and call setAutoPipMode method. This needs at least API level 31.

import 'package:simple_pip_mode/simple_pip.dart';

class MyWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return IconButton(
      icon: Icon(Icons.picture_in_picture),
      onPressed: () => SimplePip().setAutoPipMode(),
    );
  }
}

This way, when user presses home (or uses home gesture), the app enters PIP mode automatically.

Enabling callbacks

There's two ways of enabling callbacks:

• Activity wrapper (Recommended!)
• Callback helper

Activity wrapper

This is the easiest way to enable the callbacks.

Just import the wrapper class in your main activity file, and inherit from it.

Kotlin

import cl.puntito.simple_pip_mode.PipCallbackHelperActivityWrapper

class MainActivity: PipCallbackHelperActivityWrapper() {
}

Java

import cl.puntito.simple_pip_mode.PipCallbackHelperActivityWrapper;

class MainActivity extends PipCallbackHelperActivityWrapper {
}

Done! now you can use PIP callbacks and the PIP widget.

Callback helper

If something went wrong with Activity wrapper or you don't want to wrap your activity, you can enable callbacks using the callback helper.

To do so, in your main activity file import the callback helper.

import cl.puntito.simple_pip_mode.PipCallbackHelper

Instance a callback helper, provide the flutter engine to it, and finally, call helper on callback.

Kotlin

class MainActivity: FlutterActivity() {
  //...
  private var callbackHelper = PipCallbackHelper()
  //...
  override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
    super.configureFlutterEngine(flutterEngine)
    callbackHelper.configureFlutterEngine(flutterEngine)
  }
  
  override fun onPictureInPictureModeChanged(active: Boolean, newConfig: Configuration?) {
    callbackHelper.onPictureInPictureModeChanged(active)
  }
  //...
}

Java

public class MainActivity extends FlutterActivity {
    //...
    private final PipCallbackHelper callbackHelper = new PipCallbackHelper();
    //...
    @Override
    public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
        super.configureFlutterEngine(flutterEngine);
        callbackHelper.configureFlutterEngine(flutterEngine);
    }
    
    @Override
    public void onPictureInPictureModeChanged(boolean active, Configuration newConfig) {
        callbackHelper.onPictureInPictureModeChanged(active);
    }
    //...
}

Done! now you can use PIP callbacks and the PIP widget.

Using callbacks

To use callbacks, just pass them as parameters to SimplePip constructor.

SimplePip _pip = SimplePip(
  onPipEntered: () => doSomething(),
  onPipExited: () => doSomeOtherThing(),
);

Using the PIP widget

To use the widget, you need to enable callbacks first. Import pip_widget.dart file.

Add a PipWidget widget to your tree and give it a builder or a child, and a pipBuilder or a pipChild.

import 'package:simple_pip_mode/pip_widget.dart';
class MyWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return PipWidget(
      builder: (context) => Text('This is built when PIP mode is not active'),
      child: Text('This widget is not used because builder is not null'),
      //pipBuilder: (context) => Text('This is built when PIP mode is active'),
      pipChild: Text('This widget is used because pipBuilder is null'),
    );
  }
}

You can also pass callbacks directly to PipWidget.

Using PIP Actions

To use PIP actions, you need to specify a pipLayout preset on your PipWidget. The current available action layout presets are focused on giving support to media reproduction controls. They are media, media_only_pause and media_live. Those are defined on the [PipActionsLayout] enum.

You can also add a onPipAction listener to handle actions callbacks from PipWidget. This can be defined on SimplePip(onPipAction: ...) too.

import 'package:simple_pip_mode/pip_widget.dart';
import 'package:simple_pip_mode/actions/pip_action.dart';
import 'package:simple_pip_mode/actions/pip_actions_layout.dart';
class MyWidget extends StatelessWidget {
  ExampleVideoPlayer videoPlayer = ExampleVideoPlayer();
  Widget build(BuildContext context) {
    return PipWidget(
      pipLayout: PipActionsLayout.media,
      onPipAction: (action) {
        switch (action) {
          case PipAction.play:
            // example: videoPlayerController.play();
            break;
          case PipAction.pause:
            // example: videoPlayerController.pause();
            break;
          case PipAction.next:
            // example: videoPlayerController.next();
          case PipAction.previous:
            // example: videoPlayerController.previous();
          default:
            break;
        }
      },
      pipChild: videoPlayer,
      child: videoPlayer,
    );
  }
}

Notes

Multi-platform apps

Every SimplePip method calls android native code, so make sure you only make a call to a SimplePip method when running in an Android device. This includes SimplePip.isPipAvailable.

Calling SimplePip methods on a non-Android device will raise a MissingPluginException error.

Huge thanks to Erick Daros for PIP Actions feature.

I'm currently working on more features, so issues and pull requests are appreciated!
