Flutter Android Lifecycle Plugin

A Flutter plugin for Android to allow other Flutter plugins to access Android Lifecycle objects in the plugin's binding.

The purpose of having this plugin instead of exposing an Android Lifecycle object in the engine's Android embedding plugins API is to force plugins to have a pub constraint that signifies the major version of the Android Lifecycle API they expect.

	Android
Support	SDK 16+

Installation

Add flutter_plugin_android_lifecycle as a dependency in your pubspec.yaml file.

Example

Use a FlutterLifecycleAdapter within another Flutter plugin's Android implementation, as shown below:

import androidx.lifecycle.Lifecycle;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.embedding.engine.plugins.FlutterPlugin;
import io.flutter.embedding.engine.plugins.activity.ActivityAware;
import io.flutter.embedding.engine.plugins.FlutterPlugin.FlutterPluginBinding;
import io.flutter.embedding.engine.plugins.lifecycle.FlutterLifecycleAdapter;

public class MyPlugin implements FlutterPlugin, ActivityAware {
  @Override
  public void onAttachedToActivity(ActivityPluginBinding binding) {
    Lifecycle lifecycle = FlutterLifecycleAdapter.getActivityLifecycle(binding);
    // Use lifecycle as desired.
  }

  //...
}
