public NewEngineIntentBuilder(@NonNull Class<? extends FlutterActivity> activityClass)
NewEngineIntentBuilder
to be used by subclasses of
FlutterActivity
.
Subclasses of FlutterActivity
should provide their own static version of FlutterActivity.withNewEngine()
, which returns an instance of NewEngineIntentBuilder
constructed
with a Class
reference to the FlutterActivity
subclass, e.g.:
return new NewEngineIntentBuilder(MyFlutterActivity.class);
@NonNull public FlutterActivity.NewEngineIntentBuilder initialRoute(@NonNull String initialRoute)
FlutterFragment
, defaults to
"/".@NonNull public FlutterActivity.NewEngineIntentBuilder backgroundMode(@NonNull FlutterActivityLaunchConfigs.BackgroundMode backgroundMode)
FlutterActivity
's background, either FlutterActivityLaunchConfigs.BackgroundMode.opaque
or
FlutterActivityLaunchConfigs.BackgroundMode.transparent
.
The default background mode is FlutterActivityLaunchConfigs.BackgroundMode.opaque
.
Choosing a background mode of FlutterActivityLaunchConfigs.BackgroundMode.transparent
will configure the inner
FlutterView
of this FlutterActivity
to be configured with a FlutterTextureView
to support transparency. This choice has a non-trivial performance
impact. A transparent background should only be used if it is necessary for the app design
being implemented.
A FlutterActivity
that is configured with a background mode of FlutterActivityLaunchConfigs.BackgroundMode.transparent
must have a theme applied to it that includes the following
property: <item name="android:windowIsTranslucent">true</item>
.
