образец экрана видеопроигрывателя прилагается ниже Как я могу заставить проигрыватель видео воспроизводиться динамически, при этом щелкнув по списку, воспроизвести видео, передав URL-адрес видео?
пока я нажал кнопку "Пройти" URL и попытался повторно инициализировать и начать играть его не работает, состояние не меняется
Вот мой код,
videoplayerscreen.dart,
class VideoPlayerScreen extends StatefulWidget {
int playBackTime;
int playBackTotalTime;
String setPlayTime;
String setPlayDuration;
double aspectRatio;
String videoUrl;
bool isForward;
bool isFullScreen;
bool allowFullScreen;
bool showControls;
bool isAutoPlay;
int startWithinSeconds;
VideoPlayerScreen({
Key key,
this.playBackTime = 0,
this.playBackTotalTime = 0,
this.setPlayTime = "00:00",
this.setPlayDuration = "00:00",
this.aspectRatio = 16 / 9,
this.videoUrl =
"",
this.isForward = true,
this.isFullScreen = false,
this.allowFullScreen = false,
this.showControls = true,
this.isAutoPlay = false,
this.startWithinSeconds = 0,
}) : super(key: key);
@override
_VideoPlayerScreenState createState() => _VideoPlayerScreenState();
}
class _VideoPlayerScreenState extends State<VideoPlayerScreen> {
VideoPlayerController _controller;
void initPlayer() async {
_controller = VideoPlayerController.network(widget.videoUrl);
await _controller.initialize();
_controller.setLooping(true);
_controller.seekTo(Duration(seconds: widget.startWithinSeconds));
if (widget.isAutoPlay) {
_controller.play();
}
_controller.addListener(() {
setState(() {
widget.playBackTime = _controller.value.position.inSeconds;
widget.setPlayTime = timeFormatter(widget.playBackTime);
});
});
}
@override
void initState() {
initPlayer();
super.initState();
}
@override
void dispose() {
_controller.dispose();
SystemChrome.setPreferredOrientations([
DeviceOrientation.landscapeRight,
DeviceOrientation.landscapeLeft,
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
]);
super.dispose();
}
В конфигурации,
video_player: ^0.10.5
