parseClassName static method

Map<String, dynamic> parseClassName(
  1. String className,
  2. String componentType,
  3. BuildContext context
)

Parse className string and return style properties.

className - Space-separated class names componentType - Type of component for specific parsing context - Build context for responsive design

Implementation

static Map<String, dynamic> parseClassName(
  String className,
  String componentType,
  BuildContext context,
) {
  if (className.isEmpty) return {};

  // 生成缓存键
  final screenWidth = MediaQuery.of(context).size.width;
  final cacheKey = '$className:$componentType:$screenWidth';

  // 生产环境使用缓存，开发环境每次重新解析以支持热重载
  // if (kDebugMode) {
  //   print('🔥 DEBUG模式: 重新解析样式 - $className (缓存大小: ${_cache.length})');
  // }

  if (!kDebugMode && _cache.containsKey(cacheKey)) {
    return Map<String, dynamic>.from(_cache[cacheKey]!);
  }

  var styles = <String, dynamic>{};

  // 解析响应式类名
  List<String> classes = _filterResponsiveClasses(className.split(' '), context);

  // 解析基础样式
  for (String cls in classes) {
    cls = cls.trim();
    if (cls.isEmpty) continue;

    _parseBasicStyles(cls, styles);
  }

  // 处理渐变背景
  _processGradient(styles);

  // 生产环境缓存结果
  if (!kDebugMode) {
    _cache[cacheKey] = Map<String, dynamic>.from(styles);
  }

  return styles;
}
