我最初可以加載視頻，但是當我 setState 更改點擊時的 youtube 鏈接時，它不起作用，不知道為什么。按下按鈕時更改視頻的方法是什么？我正在使用 Pod Player 插件。 就像這張圖片中的加載視頻按鈕功能一樣
import 'package:flutter/material.dart';
import 'package:pod_player/pod_player.dart';
class VideoPlayer extends StatefulWidget {
const VideoPlayer({Key? key}) : super(key: key);
@override
State<VideoPlayer> createState() => _VideoPlayerState();
}
class _VideoPlayerState extends State<VideoPlayer> {
String YTLink = "https://youtu.be/A3ltMaM6noM";
late final PodPlayerController controller;
@override
void initState() {
controller = PodPlayerController(
playVideoFrom: PlayVideoFrom.youtube(YTLink),
)..initialise();
super.initState();
}
@override
void dispose() {
controller.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: ListView(
children: [
PodVideoPlayer(controller: controller),
OutlinedButton(
onPressed: () {
setState(() {
YTLink =
"https://www.youtube.com/watch?v=Q98aCklzCBE&ab_channel=DWDocumentary";
});
},
child: Text("Play Another Video")),
OutlinedButton(
onPressed: () {
setState(() {
YTLink =
"https://www.youtube.com/watch?v=AnYsa_c4GxU&ab_channel=FreeDocumentary";
});
},
child: Text("Play Another Video 2")),
],
)),
);
}
}uj5u.com熱心網友回復：
不使用 setState，而是使用控制器的 changeVideo 方法。
將此添加到按鈕的 onPressed 中：
//1
`controller.changeVideo(
playVideoFrom: PlayVideoFrom.youtube(
"https://www.youtube.com/watch?v=Q98aCklzCBE&ab_channel=DWDocumentary"));`
//2
`controller.changeVideo(
playVideoFrom: PlayVideoFrom.youtube(
"https://www.youtube.com/watch?v=AnYsa_c4GxU&ab_channel=FreeDocumentary"));`
