• auto
• never

Implementation

static FloatingLabelBehavior? decodeFloatingLabelBehavior(
  dynamic value, {
  bool validate = true,
}) {
  FloatingLabelBehavior? result;

  if (value is FloatingLabelBehavior) {
    result = value;
  } else {
    _checkSupported(
      'FloatingLabelBehavior',
      [
        'always',
        'auto',
        'never',
      ],
      value,
    );

    if (value != null) {
      assert(SchemaValidator.validate(
        schemaId: '$_baseSchemaUrl/floating_label_behavior',
        value: value,
        validate: validate,
      ));
      switch (value) {
        case 'always':
          result = FloatingLabelBehavior.always;
          break;

        case 'auto':
          result = FloatingLabelBehavior.auto;
          break;

        case 'never':
          result = FloatingLabelBehavior.never;
          break;
      }
    }
  }

  return result;
