+### Use self controller UI
+
+Use `IJKPlayer`'s `controllerWidgetBuilder` params can customize UI, default use `defaultBuildIjkControllerWidget` method to get widget.
+
+The returned widget will be overwritten on the `Texture`.
+
+```dart
+IJKPlayer(
+  mediaController: IjkMediaController(),
+  controllerWidgetBuilder: (mediaController){
+    return Container(); // your controller widget.
+  },
+);
+```
+
+### Use Texture widget
+
+Use `textureBuilder` params to customize `Texture` widget, use `playerBuilder` in before 0.1.8 version.
+
+Default use `buildDefaultIjkPlayer` method, params is `context,controller,videoInfo` and reture a `Widget`.
+
+```dart
+IJKPlayer(
+  mediaController: IjkMediaController(),
+  textureBuilder: (context,mediaController,videoInfo){
+    return Texture(); /// Your `Texture` widget
+  },
+);
+```

+### 自定义控制器 UI
+
+使用`IJKPlayer`的`controllerWidgetBuilder`属性可以自定义控制器的 UI,默认使用`defaultBuildIjkControllerWidget`方法构建
+
+返回的 Widget 会被覆盖在 Texture 上

+
