我希望我的视频播放器在进入全屏时处于全屏模式。
最佳答案
您可以复制粘贴运行下面的完整代码
您可以使用包https://pub.dev/packages/auto_orientation和 https://pub.dev/packages/chewie
在 _VideoScaffoldState
的 initState()
中执行 AutoOrientation.landscapeAutoMode();
代码片段
_chewieController = ChewieController(
videoPlayerController: _videoPlayerController1,
aspectRatio: 3 / 2,
autoPlay: true,
looping: true,
routePageBuilder: (BuildContext context, Animation<double> animation,
Animation<double> secondAnimation, provider) {
return AnimatedBuilder(
animation: animation,
builder: (BuildContext context, Widget child) {
return VideoScaffold(
...
class _VideoScaffoldState extends State<VideoScaffold> {
@override
void initState() {
SystemChrome.setPreferredOrientations([
DeviceOrientation.landscapeRight,
DeviceOrientation.landscapeLeft,
]);
AutoOrientation.landscapeAutoMode();
super.initState();
}
