Answer 1

卸载应用程序然后重新安装，如果问题仍然存在，也许您正在使用 super 覆盖 MainActivity 上的任何方法，例如对我来说添加 super onActivity 结果有帮助，这是我从这个链接找到的。

参考链接https://github.com/flutter/flutter/issues/19103#issuecomment-412647536

  override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
    super.onActivityResult(requestCode, resultCode, data); // had to add this line.
