每当我尝试包含flutter geolocation
(https://github.com/loup-v/geolocation)插件时,我都会遇到以下错误。

出了什么问题?

我可以建议帮助你做三件事。第一种是首先运行flutter clean
然后再次运行来进行完全重建。偶尔会有一些事情在颤动之间变得混乱。安卓,这有帮助。
我要做的下一件事是检查您是否获得了所有Play服务的相同版本。出于某种原因,gradlew有时会混淆。从gradlew app:dependencies
运行android
(如果你在mac / linux上,则运行./gradlew
)。如果您获得了不同的版本,请将它们全部添加为相同版本的依赖项。
例如,在我的android/app/build.gradle
中,我必须设置
implementation 'com.google.android.gms:play-services-base:15.0.2'
implementation 'com.google.android.gms:play-services-vision:15.0.2'
尽管Gradle应该对此进行排序。特别要注意com.google.android.gms:play-services-location
,因为它是地理定位包的依赖关系。 com.android.support
库也是如此。
如果仍然无效,请尝试直接运行gradle构建,特别是查看堆栈跟踪(gradlew app:build --stacktrace
文件夹中的android
)以查看它是否告诉您任何内容。然后你可以发布它,或者看看通用的Android问题以获得解决方案。可能你需要启用multi-dex,尽管我不这么认为。

我认为这是firebase的geolocation gradle版本和你的flutter版本不兼容的问题。尝试将multiDexEnabled true
添加到您的构建gradle。如果这不解决它在android studio中打开你的flutters android项目并转到geolocation build gradle并将依赖版本更改为classpath 'com.android.tools.build:gradle:3.1.2'
&在底部将播放服务更新为api "com.google.android.gms:play-services-location:15.+"
。

最后,我按照@rmtmckenzie提到的步骤解决了这个问题。
在我android/app/build.gradle
我添加了以下代码&
configurations.all {
resolutionStrategy {
force 'com.google.android.gms:play-services-location:15.0.1'
}
}
并启用multiDexEnabled true
defaultConfig {
multiDexEnabled true
}
现在使用此设置,我的整个应用程序正常运行。

在应用的顶级build.gradle中更新类路径。为了我 classpath'com.android.tools.build:gradle:3.5.3'工作正常。
