Support Android Gradle plugin 7.3.0

[asaarnak]

Since Android Gradle plugin 7.3.0 minimum Kotlin plugin version is 1.5.20 https://developer.android.com/studio/releases/gradle-plugin#min-kotlin-version

Building app gives error: The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher. The following dependencies do not satisfy the required version: project ':maps_launcher' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

For anyone else with this problem, feel free to use my fork.

maps_launcher:
  git:
    url: https://github.com/jbacco/flutter-maps-launcher
    ref: master # Fix for: https://github.com/pikaju/flutter-maps-launcher/issues/27

Or if you want to fork it yourself, just go into the android/build.gradle file and change:

ext.kotlin_version = '1.3.50'

to

ext.kotlin_version = '1.6.10'

Alternatively:

  Future<void> _launchMap(String query) async {
    if (Platform.isAndroid) {
      await launchUrl(Uri(scheme: 'geo', host: '0,0', queryParameters: {'q': query}));
    } else if (Platform.isIOS) {
      await launchUrl(Uri.https('maps.apple.com', '/', {'q': query}));
    } else {
      await launchUrl(Uri.https('www.google.com', '/maps/search/', {'api': '1', 'query': query}));
    }
  }
