Member Function Documentation

ensureInitializationComplete()

static void io.flutter.view.FlutterMain.ensureInitializationComplete ( @NonNull Context  applicationContext, @Nullable String[]  args  )

inlinestatic

Blocks until initialization of the native system has completed.

Calling this method multiple times has no effect.

Parameters

applicationContext	The Android application context.
args	Flags sent to the Flutter runtime.

Definition at line 75 of file FlutterMain.java.

                                                                    {
    FlutterInjector.instance()
        .flutterLoader()
        .ensureInitializationComplete(applicationContext, args);
  }

ensureInitializationCompleteAsync()

static void io.flutter.view.FlutterMain.ensureInitializationCompleteAsync ( @NonNull Context  applicationContext, @Nullable String[]  args, @NonNull Handler  callbackHandler, @NonNull Runnable  callback  )

inlinestatic

Same as ensureInitializationComplete(Context, String[]) but waiting on a background thread, then invoking callback on the callbackHandler.

Definition at line 86 of file FlutterMain.java.

                                  {
    FlutterInjector.instance()
        .flutterLoader()
        .ensureInitializationCompleteAsync(applicationContext, args, callbackHandler, callback);
  }

findAppBundlePath() [1/2]

static String io.flutter.view.FlutterMain.findAppBundlePath ( )

inlinestatic

Definition at line 97 of file FlutterMain.java.

                                           {
    return FlutterInjector.instance().flutterLoader().findAppBundlePath();
  }

findAppBundlePath() [2/2]

static String io.flutter.view.FlutterMain.findAppBundlePath ( @NonNull Context  applicationContext )

inlinestatic

Definition at line 103 of file FlutterMain.java.

                                                                              {
    return FlutterInjector.instance().flutterLoader().findAppBundlePath();
  }

getLookupKeyForAsset() [1/2]

static String io.flutter.view.FlutterMain.getLookupKeyForAsset ( @NonNull String  asset )

inlinestatic

Returns the file name for the given asset. The returned file name can be used to access the asset in the APK through the android.content.res.AssetManager API.

Parameters

asset

the name of the asset. The name can be hierarchical

Returns

the filename to be used with android.content.res.AssetManager

Definition at line 115 of file FlutterMain.java.

                                                                   {
    return FlutterInjector.instance().flutterLoader().getLookupKeyForAsset(asset);
  }

getLookupKeyForAsset() [2/2]

static String io.flutter.view.FlutterMain.getLookupKeyForAsset ( @NonNull String  asset, @NonNull String  packageName  )

inlinestatic

Returns the file name for the given asset which originates from the specified packageName. The returned file name can be used to access the asset in the APK through the android.content.res.AssetManager API.

Parameters

asset	the name of the asset. The name can be hierarchical
packageName	the name of the package from which the asset originates

Returns

the file name to be used with android.content.res.AssetManager

Definition at line 129 of file FlutterMain.java.

                                                                                                {
    return FlutterInjector.instance().flutterLoader().getLookupKeyForAsset(asset, packageName);
  }

startInitialization() [1/2]

static void io.flutter.view.FlutterMain.startInitialization ( @NonNull Context  applicationContext, @NonNull Settings  settings  )

inlinestatic

Starts initialization of the native system.

This loads the Flutter engine's native library to enable subsequent JNI calls. This also starts locating and unpacking Dart resources packaged in the app's APK.

Calling this method multiple times has no effect.

Parameters

applicationContext	The Android application context.
settings	Configuration settings.

Definition at line 60 of file FlutterMain.java.

                                                                       {
    FlutterLoader.Settings newSettings = new FlutterLoader.Settings();
    newSettings.setLogTag(settings.getLogTag());
    FlutterInjector.instance().flutterLoader().startInitialization(applicationContext, newSettings);
  }

startInitialization() [2/2]

static void io.flutter.view.FlutterMain.startInitialization ( @NonNull Context  applicationContext )

inlinestatic

Starts initialization of the native system.

Parameters

applicationContext

The Android application context.

Definition at line 45 of file FlutterMain.java.

                                                                              {
    FlutterInjector.instance().flutterLoader().startInitialization(applicationContext);
  }
