android - flutter image_cropper 崩溃

Question

我尝试使用此插件裁剪图像，并且在 iOS 上运行良好，但在 Android 上，应用程序会崩溃。控制台是这样说的。

有谁知道如何解决这个问题？

在 Android 平台上，我们需要将 UCropActivity 配置到应用程序下方的 AndroidManifest.xml 中。 IOS 不需要这样做。

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