• Example About Use FlutterFragment in Activity

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

the activity contains flutter fragment must special android:theme="@style/AppTheme", or render not completely

flutter fragment shouldn't in viewpager, render not completely, or maybe the problem is not special android:theme in activity

import io.flutter.embedding.android.FlutterFragment;

public class FlutterFragmentExampleActivity extends AppCompatActivity {
    @Nullable
    private FlutterFragment flutterFragment = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.flutter_fragment_example_activity);
        flutterFragment = FlutterFragment.withCachedEngine("my_engine_id")
                .shouldAttachEngineToActivity(true)
                .build();
        this.getSupportFragmentManager().beginTransaction()
                .add(R.id.flutterContainer, flutterFragment, "flutterFragment")
                .commitAllowingStateLoss();

//        new Handler().postDelayed(() -> {
//            this.getSupportFragmentManager().beginTransaction()
//                    .replace(android.R.id.content, new MineFragment(), "MineFragment")
//                    .commitAllowingStateLoss();
//            new Handler().postDelayed(() -> {
//                this.getSupportFragmentManager().beginTransaction()
//                        .add(android.R.id.content, flutterFragment, "flutterFragment")
//                        .commitAllowingStateLoss();
//            }, 3000);
