Flutter plugin to execute dart code on boot completed.

See example source in repository.

A bunch of extra things need to be done to use this plugin:

1. In your dart code, call boot_completed.setBootCompletedFunction(functionName)

   See main() in example/lib/main.dart

2. On the android side, register org.thebus.boot_completed.BootCompletedPlugin as a broadcast receiver

   See example/android/app/src/main/AndroidManifest.xml

3. On the android side, your application needs to subclass FlutterApplication, and implement PluginRegistry.PluginRegistrantCallback

   org.thebus.boot_completed.BootCompletedPlugin.setPluginRegistrantCallback(this) needs to be called,

   and PluginRegistrantCallback.registerWith should call GeneratedPluginRegistrant.registerWith()

   See example/android/app/src/main/kotlin/org/thebus/boot_completed_example/ExampleApplication.kt

   Don't forget to tell android to use your application subclass instead of FlutterApplication by modifying your AndroidManifest.xml

   See the application section in example/android/app/src/main/AndroidManifest.xml
