无法使用 flutter_local_notifications

Question

我在我的项目中使用了最新版本的 flutter_local_notifications，但一直遇到这个问题

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 中删除插件并安装来解决，在您的情况下 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') }
