Code Push/Hot update

咱們如今使用flutter更新版本

下載apk：
引入
dependencies:
flutter_downloader: 1.1.3

taskId = await FlutterDownloader.enqueue(
url: url,//服務端提供apk文件下載路徑
savedDir: (await getExternalStorageDirectory()).path.toString(),//本地存放路徑
fileName: 「xiangta_」 + netCode + 「.apk」,//存放文件名
showNotification: false,//是否顯示在通知欄
openFileFromNotification: false,//是否在通知欄能夠點擊打開此文件
);

//taskId爲任務id （與完成下載的文件成一一對應）open是執行打開 打開須要任務id 相信你已經找到方向了
FlutterDownloader.registerCallback((taskId, status, progress) {
if (status == DownloadTaskStatus.complete) {
//下載完成
FlutterDownloader.open(taskId:taskId));
} else if (status == DownloadTaskStatus.failed) {
//下載出錯
}
});

1、使用FlutterDownloader下載

2、open_file打開文件自帶安裝（FlutterDownloader自帶打開文件，但不能打開app不知道爲啥）

代碼：

一、下載監聽 

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);
      }
    });
二、下載

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();
