Steps to Reproduce

The app can't be built on Android if a plugin is only iOS targetting.
It's the case with apple_map_flutter.

I can't run my app under Android with the new release Flutter: 2.10 because the tool expect all plugins to support both Android and iOS or something like this (i have another project that builds find without apple_map_flutter)

  1. Create a new project under flutter: 2.10
  2. Add apple_maps_flutter dependency using flutter pub add apple_maps_flutter
  3. Build your app on Android device on flutter 2.10 stable/master

Expected results:

The app should be built on Android (and on iOS) even if a plugin is missing for one of the platform, as it was done before flutter: 2.10.

Actual results: 

Launching lib/main.dart on moto g 8 power in debug mode...
Running Gradle task 'assembleDebug'...
Plugin project :apple_maps_flutter not found. Please update settings.gradle.

FAILURE: Build failed with an exception.

    Hi @Tom3652, Thanks for filing the issue. I was able to reproduce the same behavior the app failed to build when using a plugin not supported for Android. This was reproducible on the latest stable/master and even on stable 2.8.1. This looks like a duplicate of #46304 (closed). Not sure if this is intended, But I was able to fix this by modifying the settings.gradle

    settings.gradle (after modification) 
    include ':app'

def localPropertiesFile = new File(rootProject.projectDir, "local.properties")
def properties = new Properties()

assert localPropertiesFile.exists()
localPropertiesFile.withReader("UTF-8") { reader -> properties.load(reader) }

def flutterSdkPath = properties.getProperty("flutter.sdk")
assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
apply from: "$flutterSdkPath/packages/flutter_tools/gradle/app_plugin_loader.gradle"

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

// Fixed by adding the lines below

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}
    flutter run stable(2.10)

    I'm very confused here.

    // Fixed by adding the lines below

    The lines you've added below that should cause this issue, not fix it. It unconditionally adds every plugin, unlike app_plugin_loader.gradle which filters by supported platform.

    @Tom3652 Could you provide the .flutter-plugins-dependencies file for a project that reproduces this?

    Yes sure @stuartmorgan :

    {"info":"This is a generated file; do not edit or check into version control.","plugins":{"ios":[{"name":"apple_maps_flutter","path":"/Users/foxtom/Desktop/flutter/.pub-cache/hosted/pub.dartlang.org/apple_maps_flutter-1.0.1/","dependencies":[]}],"android":[],"macos":[],"linux":[],"windows":[],"web":[]},"dependencyGraph":[{"name":"apple_maps_flutter","dependencies":[]}],"date_created":"2022-02-04 17:01:44.328220","version":"2.10.0"}%

    I have simply created a new project, added the apple_map_flutter and build on my android device.

    Oh, I see. This is the new code to check min SDK versions. It's still using .flutter-plugins, which is wrong; it should be using .flutter-plugins-dependencies.

    In most cases it will still work because flutter_tools/gradle/flutter.gradle does its own filtering based on the presence of a gradle file in the right place in the plugin, but that is being defeated by the fact that apple_maps_flutter has an android/ folder even though it doesn't support Android.

    We should definitely fix this on our side by updating flutter_tools/gradle/flutter.gradle to use .flutter-plugins-dependencies, but it can also be fixed by the plugin author. I'll file an issue there.

    No, it's still a bug. It's trivial for plugin developers to avoid by deleting dead/dummy android/ directories, but we shouldn't fail to build if they don't.
