image_picker 在 android 应用中崩溃 - Flutter 应用
image_picker crash in android app - Flutter App
首先，我尝试了这个 但问题仍然存在，我在新的模拟器上、在真实设备上尝试了它，但我无法修复它。
它在 IOS 上成功运行。
好的，让我们看看问题：
- 第一步有效，所以转到 gallery 我在第二步遇到问题
- 第二步：当我 select 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：

我终于找到了解决办法。
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。所以图像裁剪包需要 activity 权限才能在 AndroidManifest.xml 上添加，因此对于 android.
权限如下：
<activity
android:name="com.yalantis.ucrop.UCropActivity"
android:screenOrientation="portrait"
android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>
这里是documentation of image cropper，您可以通过查看获得更多
首先，我尝试了这个
好的，让我们看看问题：
- 第一步有效，所以转到 gallery 我在第二步遇到问题
- 第二步：当我 select 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：
