颤振插件的问题（图像裁剪器）

Question

我正在创建一个可以处理图像的应用程序，其中一些需要裁剪，而另一些则不需要。我已经添加了库：

image_cropper: ^1.3.1

我已经在 android manifest 中安装了依赖项：

<intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
        // This is wat I had to add as said in the pub.dev from icon cropper
        <activity
            android:name="com.yalantis.ucrop.UCropActivity"
            android:screenOrientation="portrait"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>
    </application>
</manifest>

但是当我运行我的应用程序时，我收到以下错误：

Launching lib\main.dart on SM N950F in debug mode...
lib\main.dart:1

FAILURE: Build failed with an exception.

这是我的 settings.gradle：

// found in the LICENSE file.
 
include ':app'
 
def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()
 
def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}
 
plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}

我也启用了 multiDex。

检查您是否有良好的互联网连接，然后再次构建项目

我有 image_cropper 工作，一个例子供你检查和比较是否一切正常。
