我试图将视频播放器放置在屏幕顶部,但始终将其放置在屏幕中央-即使我也尝试使用容器。
以下是我的飞镖文件,请检查并告知我。对于播放器,我正在使用 chewie 库作为控制器并播放网络URL。在chewie库内部,他们正在使用视频播放器插件。

super.initState();
print('url player :${widget.imageData.dataUrl}');

_videoPlayerController1 = VideoPlayerController.network('${widget.imageData.dataUrl}');
_chewieController = ChewieController(

autoPlay: true,
looping: true,

由于您希望Chewie排在首位,所以我假设您正在尝试在播放器下方添加其他小部件。
例如,您可以将Chewie嵌入到Column()
中。
默认情况下,Column()
的{{1}}属性设置为mainAxisAlignment
,这意味着子元素将从屏幕的上边缘开始向下生长。
就像这样:
MainAxisAlignment.start
也。为了使缺口和其他内容清晰可见,您可能需要将整个内容包装在Widget build(BuildContext context) {
return Scaffold(
body: Column(
children: <Widget>[
Chewie(
controller: _chewieController,
)
],
),
);
}
小部件中。
SafeArea()

将Chewie
包裹在Container
内,设置所需的height
和width
