pubspec.yaml

firebase_messaging: ^9.0.0
firebase_core: ^1.0.0
flutter_local_notifications: ^4.0.1+1

Answer 1

我终于重现了此类问题，可以通过升级或降级插件或从.pub_chace 中删除插件并安装它来解决它，在你的情况下flutter_local_notifications 。

Answer 2

打开 android\build.gradle 找到这个

子项目 { project.evaluationDependsOn(':app')

project.configurations.all {
    resolutionStrategy.eachDependency { details ->
        if (details.requested.group == 'androidx.core' &&
                !details.requested.name.contains('androidx')) {
            details.useVersion "1.0.1"
        }
    }
}

删除 project.configurations.all 及其所有内容

新代码现在看起来像这样

subprojects { project.evaluationDependsOn(':app') }

flutter 清洁 flutter 发布
