static PageTransitionsTheme? decodePageTransitionsTheme(
  dynamic value, {
  bool validate = true,
}) {
  PageTransitionsTheme? result;

  if (value is PageTransitionsTheme) {
    result = value;
  } else if (value != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/page_transitions_theme',
      value: value,
      validate: validate,
    ));

    var builders = <TargetPlatform, PageTransitionsBuilder>{};
    value['builders']?.forEach(
      (key, value) =>
          builders[decodeTargetPlatform(key)!] = decodePageTransitionsBuilder(
        value,
        validate: false,
      )!,
    );

    result = PageTransitionsTheme(
      builders: builders,
