initThemeConfig method

@override void initThemeConfig(String configId, { BaseCommonConfig? currentLevelCommonConfig, })

部分代码示意如下：

cardTitleConfig.detailTextStyle.merge(
  BrnTextStyle(
    color: commonConfig.colorTextBase,
    fontSize: commonConfig.fontSizeBase,
  ).merge(detailTextStyle),
);

- 以 `commonConfig` 字段为基础 merge `detailTextStyle`。
  `detailTextStyle` 字段优先级高，当detailTextStyle中字段（如 color）为 null 时
  会使用 `commonConfig.colorTextBase`。
- 以默认上一级配置为基础 merge 第一步的结果，当第一步中字段（如 color）为空时，
  使用上一层级配置的 color (`cardTitleConfig.detailTextStyle.color`)。

Implementation

@override
void initThemeConfig(
  String configId, {
  BaseCommonConfig? currentLevelCommonConfig,
}) {
  super.initThemeConfig(
    configId,
    currentLevelCommonConfig: currentLevelCommonConfig,
  );

  /// 用户全局组件配置
  AbnormalStateConfig abnormalStateConfig = BaseThemeConfig.instance
      .getConfig(configId: configId)
      .abnormalStateConfig;

  _titleTextStyle = abnormalStateConfig.titleTextStyle.merge(
    BaseTextStyle(
      color: commonConfig.colorTextBase,
      fontSize: commonConfig.fontSizeSubHead,
    ).merge(_titleTextStyle),
  );
  _contentTextStyle = abnormalStateConfig.contentTextStyle.merge(
    BaseTextStyle(
      color: commonConfig.colorTextHint,
      fontSize: commonConfig.fontSizeSubHead,
    ).merge(_contentTextStyle),
  );
  _operateTextStyle = abnormalStateConfig.operateTextStyle.merge(
    BaseTextStyle(
      color: commonConfig.brandPrimary,
      fontSize: commonConfig.fontSizeBase,
    ).merge(_operateTextStyle),
  );
  _singleTextStyle = abnormalStateConfig.singleTextStyle.merge(
    BaseTextStyle(
      color: commonConfig.colorTextBaseInverse,
      fontSize: commonConfig.fontSizeSubHead,
    ).merge(_singleTextStyle),
  );
  _doubleTextStyle = abnormalStateConfig.doubleTextStyle.merge(
    BaseTextStyle(
      color: commonConfig.brandPrimary,
      fontSize: commonConfig.fontSizeSubHead,
    ).merge(_doubleTextStyle),
  );
  _btnRadius ??= abnormalStateConfig._btnRadius;
  _singleMinWidth ??= abnormalStateConfig._singleMinWidth;
  _doubleMinWidth ??= abnormalStateConfig._doubleMinWidth;
