Question

I am trying to add firebase dependencies. When I run flutter run I get

You can find which package depends on google_api_availability by running flutter packages pub deps on the root of the project - this will list all the direct and transitive dependencies of your project in a tree view.

I couldn't find a way to display the plugin dependencies of a package - I guess you'll only find out once you try to build it.

The problem is you are using version 3.3.1 of the Android Gradle plugin, which enforces Kotlin 1.3.0 or above. At the same time, the geolocator package depends on google_api_availability, which seems to be using Kotlin 1.2.71. At the moment there is no version of google_api_availability that uses Kotlin 1.3.0 or above, so you only have 1 solution - downgrade the Android Gradle plugin to version 3.2.1.

Solution 2

   buildscript {
    ext.kotlin_version = '1.6.10' //-> i added
    repositories {
        google()
        mavenCentral()
    }

dependencies {
  classpath 'com.android.tools.build:gradle:4.1.3'
  classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"//->added

}

Just added the two line above to build.gradle and it worked. Even if there is a warning like;"Kotlin version that is used for building with Gradle (1.6.10) differs from the one bundled into the IDE plugin (1.3.72) " Anyway i think i need to update IDE plugin soon.

Solution 3

In android folder you shall see file named as build.gradle

You would see a piece of code

buildscript {
    ext.kotlin_version = 'x.x.xx'
    repositories {
        google()
        jcenter()
    }

edit the version of property ext.kotlin_version by replacing x.x.xx with 1.3.10

This should help you in resolve the error

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher.
The following dependencies do not satisfy the required version:
project ':google_api_availability' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

The solution we used was to include the package and all their dependency directly in the flutter build environment. !! This might not be ideal in the long run, but will help you while this AndroidX migration is happening and messing with your builds.

In the pubspec.yaml we included specific versions like so

geolocator: 3.0.0               # AndroidX - Breaking! 
google_api_availability: 1.0.6  # Geolocator Dependency. 
meta: 1.1.6                     # Geolocator Dependency. 
permission_handler: 2.2.0       # Geolocator & Meta Dependency.

The breakage for us happend between the google_api_availability v1.0.6 and v2.0.0

You can find which package depends on google_api_availability by doing as Ovidiu sayes or by opening https://pub.dartlang.org/ and type "dependency:google_api_availability" in the search bar. Also on each package page you can see the dependency and who depends on them.

I just had to change the kotlin_version in android/build.gradle file:

buildscript {
    // change here:
    ext.kotlin_version = '1.3.21'
    dependencies {
        // kotlin version is used here:
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

After the changes in BuildScript and dependencies, the error is gone.

Right now, this is the better approach. Just adding google_api_availability: 1.0.6 to pubspec.yaml is enough.
