        "iOS deployment target must be bumped to 14.0 (Runner target in Xcode, and the Podfile platform line if a Podfile exists)",
        "Identifies the iOS deployment target as the single most common iOS build failure cause",
        "Android minSdk must be 21 or higher",
        "Does NOT insist CocoaPods is required — mentions that the plugin supports both CocoaPods and SPM and Flutter chooses automatically (or simply does not force one)",

        "Read it in Dart with `const accessToken = String.fromEnvironment('ACCESS_TOKEN');`",
        "Call `MapboxOptions.setAccessToken(accessToken)` in `main()` before `runApp`, so the token is set before any `MapWidget` is created",
        "Does NOT suggest hard-coding the token in source code or putting it in pubspec.yaml",

        "Register the asset path under `flutter: assets:` in pubspec.yaml",

      "expectations": [
        "Most likely cause: `MapboxOptions.setAccessToken(...)` is never called, or is called after the `MapWidget` is already built",
        "Verify the token is read with `String.fromEnvironment('ACCESS_TOKEN')` using the exact same key passed to --dart-define",
        "Call `MapboxOptions.setAccessToken(...)` in `main()` before `runApp`",
        "Confirm the token is a public token (starts with `pk.`) and has not been revoked",
