flutter 集成极光推送报 is provided解决办法

flutter 集成极光推送 jpush_flutter: ^2.4.4报下面错误

Error：Attribute application@name at AndroidManifest.xml:5:9-42 requires a placeholder substitution but no value for <applicationName> is provided.

需要在android/app/build.gradle文件下新增代码

极光AndroidManifest变量

原代码

manifestPlaceholders = [
        JPUSH_PKGNAME : applicationId,
        JPUSH_APPKEY : "appkey", // NOTE: JPush 上注册的包名对应的 Appkey.
        JPUSH_CHANNEL : "developer-default", //暂时填写默认值即可.

需要修改为

manifestPlaceholders = manifestPlaceholders +[
        JPUSH_PKGNAME : applicationId,
        JPUSH_APPKEY : "appkey", // NOTE: JPush 上注册的包名对应的 Appkey.
        JPUSH_CHANNEL : "developer-default", //暂时填写默认值即可.
