Enum FlutterView.TransparencyMode

java.lang.Object

java.lang.Enum<FlutterView.TransparencyMode>

io.flutter.embedding.android.FlutterView.TransparencyMode

All Implemented Interfaces:

Serializable, Comparable<FlutterView.TransparencyMode>

Enclosing class:

FlutterView

Deprecated.

@Deprecated
public static enum FlutterView.TransparencyMode
extends Enum<FlutterView.TransparencyMode>

Transparency mode for a FlutterView.

Deprecated - please use TransparencyMode instead.

TransparencyMode impacts the visual behavior and performance of a FlutterSurfaceView, which is displayed when a FlutterView uses RenderMode.surface.

TransparencyMode does not impact FlutterTextureView, which is displayed when a FlutterView uses RenderMode.texture, because a FlutterTextureView automatically comes with transparency.

Enum Constant Detail

opaque

public static final FlutterView.TransparencyMode opaque

Deprecated.

Renders a FlutterView without any transparency. This affects FlutterViews in RenderMode.surface by introducing a base color of black, and places the FlutterSurfaceView's Window behind all other content.

In RenderMode.surface, this mode is the most performant and is a good choice for fullscreen Flutter UIs that will not undergo Fragment transactions. If this mode is used within a Fragment, and that Fragment is replaced by another one, a brief black flicker may be visible during the switch.

transparent

public static final FlutterView.TransparencyMode transparent

Deprecated.

Renders a FlutterView with transparency. This affects FlutterViews in RenderMode.surface by allowing background transparency, and places the FlutterSurfaceView's Window on top of all other content.

In RenderMode.surface, this mode is less performant than opaque, but this mode avoids the black flicker problem that opaque has when going through Fragment transactions. Consider using this TransparencyMode if you intend to switch Fragments at runtime that contain a Flutter UI.

Method Detail

values

public static FlutterView.TransparencyMode[] values()

Deprecated.

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FlutterView.TransparencyMode c : FlutterView.TransparencyMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FlutterView.TransparencyMode valueOf(String name)

Deprecated.

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
