• Example About Use FlutterFragment in Activity

shouldAttachEngineToActivity(true) // must be true, or flutter plugin activiy is null

import io.flutter.embedding.android.FlutterFragment;

        flutterFragment = FlutterFragment.withCachedEngine("my_engine_id")
                .shouldAttachEngineToActivity(true) // must be true, or flutter plugin activiy is null
                .build();
