Setup Android

Use a compatible Kotlin version​

Ensure that you are using Kotlin version 1.9.0 or newer. You can check the most recent Kotlin version on kotlinlang.org.

(new) Gradle with a declarative plugins block​

Open android/settings.gradle and set the Kotlin version like this:

android/settings.gradle
plugins {
    // ...
    id "org.jetbrains.kotlin.android" version "1.9.0" apply false
}

In case you can't find the plugins {} block your app still uses the old apply script method.

(old) In a legacy apply script gradle file​

Open android/app/build.gradle and set the Kotlin version like this:

android/app/build.gradle
buildscript {
    ext.kotlin_version = '1.9.0'
    // ...
}

Adjust the minSdk version of Android​

The maplibre package on Flutter uses platform views to display the native map. This requires an Android SDK version of at least 23 (Android 6.0).

tip

The app compiles with a minSdk version of down to 21. However, the MapLibre map won't be visible on these Android versions. You can check for the SDK version with device_info_plus and render an alternative map as a workaround or limit the supported Android versions to Android 6.0 and onwards like demonstrated here.

Open your android/app/build.gradle file and ensure that it is set to 23 or higher.

android/app/build.gradle
android {
    defaultConfig {
        // ...
        minSdk = 23 // previously flutter.minSdkVersion
        // ...
    }
}

Set the permissions​

If you want to show the user's location on the map you need to add the permissions in the application manifestandroid/app/src/main/AndroidManifest.xml.

android/app/src/main/AndroidManifest.xml

<manifest>
    <!-- Always include this permission -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <!-- Include only if your app benefits from precise location access. -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
</manifest>

Starting from Android API level 23 you also need to request it at runtime. This plugin does not handle this for you. You can either use the flutter package location or permission_handler for this.
