我们是否可以下载视频并使用flutter播放，而无需将其添加到资源中？

import 'package:dio/dio.dart';

void downloadVideo(String url, String savePath) async {
  Dio dio = Dio();
  
  try {
    Response response = await dio.get(url, options: Options(responseType: ResponseType.bytes));
    File file = File(savePath);
    await file.writeAsBytes(response.data);
    print('视频下载完成');
  } catch (e) {
    print('视频下载失败: $e');
  }
}

void main() {
  String videoUrl = 'https://example.com/video.mp4';
  String savePath = '/path/to/save/video.mp4';
  
  downloadVideo(videoUrl, savePath);
}

import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';

void playDownloadedVideo(String videoPath) {
  VideoPlayerController controller = VideoPlayerController.file(File(videoPath));
  
  controller.initialize().then((_) {
    controller.play();
  });
  
  runApp(
    MaterialApp(
      home: Scaffold(
        body: Center(
          child: AspectRatio(
            aspectRatio: controller.value.aspectRatio,
            child: VideoPlayer(controller),
          ),
        ),
      ),
    ),
  );
}

void main() {
  String downloadedVideoPath = '/path/to/save/video.mp4';
  
  playDownloadedVideo(downloadedVideoPath);
}
