刚开始用的OtaUpdate插件,插件内部使用downloadmanager实现的国内有很多机型不支持
思路:不想自己造轮子 使用网上现有插件
一、使用FlutterDownloader下载
二、open_file打开文件自带安装(FlutterDownloader自带打开文件,但不能打开app不知道为啥)
代码:
1、下载监听
FlutterDownloader.registerCallback((id, status, progress) { print( 'Download task ($id) is in status ($status) and process ($progress)'); if (status == DownloadTaskStatus.complete) { OpenFile.open(_localPath); FlutterDownloader.open(taskId: id); } });
2、下载
final taskId = await FlutterDownloader.enqueue( url: url, savedDir: _localPath, showNotification: true, // show download progress in status bar (for Android) openFileFromNotification: true, // click on notification to open downloaded file (for Android) ); final tasks = await FlutterDownloader.loadTasks();
