问题描述
我是 flutter 的新手，我构建了一个显示当前纬度和经度的很小的应用程序，这需要我在 pubspec.yaml 中添加两个依赖项:-
I am new to flutter and i build a very little app showing current latitude and longitude which required me to add two dependencies in pubspec.yaml :-
location 和 simple_permissions 获取当前用户位置并请求位置权限.
location and simple_permissions to get current user location and asking for location permission.
但是当我运行该应用程序时，它显示以下错误:-
but when i ran the app it shows following error:-
Gradle task 'assembleDebug'...

BUILD FAILED in 9s
Finished with error: Gradle task assembleDebug failed with exit code 1
我认为这是因为添加了两次库，但我没有手动添加依赖项，因此内部出现抖动错误.
i think it is because of adding a library two times but i am not adding dependencies manually so it is flutter error inside.
请告诉我解决方法

推荐答案
这个 gradle 错误消息太难解决了...好吧，我遇到了一些这样的问题，我写了我如何解决 此处.无论如何，我建议您在 pubspec 中使用更新的软件包.simple_permissions 包已经有一段时间没有更新了，请尝试使用 permission_handler 包代替.避免未来构建问题的另一点是将您的应用程序迁移到 androidX 并使用已经使用 androidX 的依赖项，许多官方插件正在迁移到它，当我们在同一个项目中将支持库与 androidX 混合时，构建过程会很遗憾地失败.如果您计划在您的应用中包含 google_maps，我真的建议您迁移到 androidX 而避免它.
This gradle error messages are so hard to solve... Well I had some problems like this and I wrote how I solved here. Anyway I advise you to use updated packages in your pubspec. simple_permissions package has been a while there is no updates, try permission_handler package instead. Other point to avoid future build problems is migrate your app to androidX and use dependencies which already using androidX too, a lot of official plugins are migrating to it and when we mix support library with androidX in the same project the build process fails sadly. If you are planning include google_maps in you app I really recommend you migrate to androidX instead avoid it.
AndroidX 是具有其他命名空间的原始支持库包和类.完整说明此处.
AndroidX is the original support library packages and classes with other namespace. Full description here.
您可以手动迁移到 androidx，也可以使用有时会失败的 android-studio 迁移工具.已在此处中描述了使用 android-studio 工具的迁移过程详情.
You can migrate to androidx manually or you can use android-studio migration tool that some times fails. A migration process with android-studio tools has been already described here in details.
要手动迁移，您需要用相应的 androidx 包替换所有支持库依赖项.一个例子是:
To migrate manually you need replace all your support library dependencies by respective androidx package. An example is:
dependencies {
// using support library
implementation 'com.android.support:appcompat-v7:$version'
}
必须替换为
dependencies {
// using androidx
implementation 'androidx.appcompat:appcompat:$version' //androidx artifact
}
Androidx 工件映射可以在此处找到在您的 gradle.properties 文件中，您需要在下面插入这两行
Androidx artifact mappings can be found here In your gradle.properties file you need insert this two lines below
android.enableJetifier=true
android.useAndroidX=true
并确保您的 Flutter 依赖项也使用了 androix.
And make sure your flutter dependencies are using androix too.
看一看 this flutter page it talk关于 androidX 兼容性和迁移.
Take a look at this flutter page it talks about androidX compatibility and migration.
希望能帮到你.
