testFlutterLoaderCallbackWhenInitializedTwice()

void dev.flutter.scenarios.TestActivity.testFlutterLoaderCallbackWhenInitializedTwice ( )

inlineprotected

This method verifies that io.flutter.embedding.engine.loader.FlutterLoader#ensureInitializationCompleteAsync(Context, String[], Handler, Runnable) invokes its callback when called after initialization.

Definition at line 86 of file TestActivity.java.

                                                                 {
