我遇到这个错误

Error: Attribute application@label value=(flutter_bloc_pattern) from AndroidManifest.xml:18:9-45 is also present at [:DynamsoftBarcodeReader] AndroidManifest.xml:13:9-41 value=(@string/app_name).

构建失败并出现错误

我的 list 是这样的

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

Answer 1

错误信息告诉你在你AndroidManifest.xml你的android:label具有值(value) flutter_bloc_pattern已经存在于(库/插件/项目)DynamsoftBarcodeReader 的 list 中.

您可以按照错误提示添加 tools:replace="android:label"给你的<application> list 中的节点

<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您还需要添加模式的属性

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