flutter - android 应用程序中的 image_picker 崩溃 - Flutter 应用程序

Question

首先，我尝试了这个 answer但问题仍然存在，我在真实设备上的新模拟器上尝试过，但无法修复。它在 IOS 上成功运行。

好吧，让我们看看问题:

• 第一步是工作，所以去 gallery 我在第二步遇到问题
• 第二步:当我选择一张图片时，VS Code 失去了与设备的连接，因此应用程序崩溃了。 Emulator Photo When It Crash

这是输出:

Answer 1

我终于找到了解决方案。我也遇到了这个问题，这个解决方案对我有帮助。这里的问题是图像裁剪包。所以image cropper package需要在AndroidManifest.xml上添加一个activity权限，所以对于android.

这里是权限:

<activity
    android:name="com.yalantis.ucrop.UCropActivity"
    android:screenOrientation="portrait"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

这里是 documentation of image cropper ，你可以通过查看获得更多
