minSdk function

Future<int?> minSdk({ String prefixPath = '.', })

Retrieves the minSdk value for the project rooted at prefixPath.

Probes, in order:

1. App-level gradle file via findAndroidGradleFile (KTS preferred over Groovy). Tries multiple minSdk regex patterns appropriate for the detected DSL.
2. If a flutter.minSdkVersion indirection is detected, recurses into the Flutter SDK gradle file located via flutter.sdk in local.properties.
3. Falls back to a flutter.minSdkVersion=... line in local.properties.

Returns null when none of the probes yield a value (caller falls back to constants.androidDefaultAndroidMinSDK).

Known limitations (return null → user must specify min_sdk_android):

• Version catalogs (libs.versions.toml references like libs.versions.minSdk.get().toInt()).
• Convention plugin delegation.

Implementation

Future<int?> minSdk({String prefixPath = '.'}) async {
  final detection = await detectMinSdkAndroid(prefixPath: prefixPath);
  return detection.value;
}
