Flutter android应用程序中的图像拾取程序崩溃-颤振应用程序

首先，我试过这个，但问题仍然存在，我在新的模拟器上试过，在真实的设备上试过，但我无法修复它。 并且它在IOS上成功运行

好,我们来看看这个问题:

• 第一步是有效的，所以进入第二步我面临一个问题
• 第二步：当我选择一个图像时，VS代码会丢失与设备的连接，因此应用程序会崩溃

以下是输出：

我终于找到了解决办法。 我也面临这个问题，这个解决方案对我很有帮助。这里的问题是图像裁剪器包。因此，图像裁剪程序包需要一个活动权限才能添加到

AndroidManifest.xml

，对于android也是如此

这里是权限：

，您可以通过查看
运行
颤振清理
一次并重试来获取更多信息。请确认在manifirst中声明活动无法找到显式活动类{com.example.gayidayi/com.yalantis.ucrop.UCropActivity}；你在AndroidManifest.xml中声明过这个活动吗？我不知道怎么做，你能提供一些源代码或文档吗？或者直接放一个answer@Steve55您正在使用任何额外的插件，如用于裁剪图像或任何？是的，我正在使用
