launch method

@override Future<void> launch(String url, { String? androidPackageName, })

Launch a URL. Opens in the native app if it handles the URL, otherwise opens in the default browser.

On Android, androidPackageName targets the specific app package so the system resolver doesn't open a different app (e.g. Go vs Maps).

Implementation

@override
Future<void> launch(String url, {String? androidPackageName}) async {
  final uri = Uri.tryParse(url);
  if (uri == null || !uri.hasScheme) {
    throw ArgumentError.value(url, 'url', 'Invalid URL: must have a scheme');
  }
  final ProcessResult result;
  if (Platform.isMacOS) {
    result = await Process.run('open', [url]);
  } else if (Platform.isWindows) {
    result = await Process.run('cmd', ['/c', 'start', '', url]);
  } else if (Platform.isLinux) {
    result = await Process.run('xdg-open', [url]);
  } else {
    throw UnsupportedError(
      'MapLauncherDesktop does not support ${Platform.operatingSystem}',
    );
  }
  if (result.exitCode != 0) {
    throw Exception('Failed to launch URL: ${result.stderr}');
  }
}
