firebase - 添加 firebase 消息传递后 flutter gradle 出错

Question

A 出现如下错误，找了很多方法解决，但不知道要用什么版本，要做什么。

The library com.google.firebase:firebase-iid is being requested by various other libraries at [[16.2.0,16.2.0]], but resolves to 15.1.0.

Answer 1

移除

 implementation 'com.google.firebase:firebase-messaging:17.0.0'

来自您的应用程序

如果有人遇到这样的错误

'com.android.support:appcompat-v7' has different version for the compile (26.1.0) and runtime (27.0.1) classpath

然后

在你的项目级gradle文件下

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "26.1.0"
            }
        }
    }
}

将以上行添加到项目级gradle文件的底部
