Implementation

const AlignmentAddonConfig(
  String alignmentName,
)   : assert(
        // Since we can only use constant values, that means we cannot use
        // an enum or the [Alignment] class from Flutter. We have to use
        // strings instead, and we have to make sure that the string is
        // one of the predefined values.
        alignmentName == 'Top Left' ||
            alignmentName == 'Top Center' ||
            alignmentName == 'Top Right' ||
            alignmentName == 'Center Left' ||
            alignmentName == 'Center' ||
            alignmentName == 'Center Right' ||
            alignmentName == 'Bottom Left' ||
            alignmentName == 'Bottom Center' ||
            alignmentName == 'Bottom Right',
      ),
      super(
        'alignment',
        'alignment:${alignmentName}',
      );
