fromJson static method

DefineSource? fromJson(Object? raw)

Reads back what toJson wrote, or null for a shape this build has no member for.

Null rather than a throw, for the reason _platformsOf gives on the app side: the config imports the flutterware version the project pins, which can run ahead of the GUI reading its manifest. A source we cannot resolve has to mean a knob with fewer suggestions, never a knob that disappears.

Implementation

static DefineSource? fromJson(Object? raw) {
  if (raw is! Map) return null;
  if (raw['source'] == 'hostAddresses') return hostAddresses;
  if (raw['source'] == 'flutterSdk') return flutterSdk;
  if (raw['script'] case String path) {
    return ScriptSource(
      path,
      args: [
        for (var arg in (raw['args'] as List? ?? const []))
          if (arg is String) arg,
      ],
    );
  }
  return null;
