添加'tools：replace =“android：label”'来 AndroidManifest.xml：16：5-39：19中的元素覆盖

Question

我收到了这个错误

错误：来自AndroidManifest.xml的属性应用程序@ label value =（flutter_bloc_pattern）：18：9-45也出现在[：DynamsoftBarcodeReader] AndroidManifest.xml：13：9-41 value =（@ string / app_name）。

构建失败并出现错误

我的清单就是这个

错误信息告诉你，在你AndroidManifest.xml你的android:label值flutter_bloc_pattern已经存在于（library / plugin / project）DynamsoftBarcodeReader的清单中。

正如错误所述，您可以将tools:replace="android:label"添加到清单中的<application>节点

<application
    tools:replace="android:label"
    android:name="io.flutter.app.FlutterApplication"
    android:label="flutter_bloc_pattern"
    android:icon="@mipmap/ic_launcher">

如果添加tools属性，还需要添加模式

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="nz.co.plumbingworld.flutterblocpattern">
