Flutter图片裁剪器崩溃

Question

我尝试使用这个插件裁剪图片，在iOS上表现很好，但在Android上，应用程序会崩溃。控制台显示如下信息。

有人知道怎么修复这个问题吗？

Answer 1

在 Android 平台上，我们需要在应用程序下面的 AndroidManifest.xml 中配置 UCropActivity。iOS 平台不需要这样做。

详细阅读： https://pub.dev/packages/image_cropper

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

我已经解决了它，用“replace”替换。

if (details.requested.group == 'com.android.support'
    && !details.requested.name.contains('multidex') ) {
    details.useVersion "27.1.1"
}
if (details.requested.group == 'androidx.core'
    && !details.requested.name.contains('androidx') ) {
    details.useVersion "1.0.1"
}
if (requested.group == "androidx") {
    if (!requested.name.startsWith("multidex")) {
        details.useVersion "${targetSdk}.+"
    }
