build method

@override Future<void> build(BuildStep buildStep)

Generates the outputs for a given BuildStep.

Implementation

@override

  final allConfigs = <String, bool>{};

  // 查找所有的.event_config.json文件
  final pattern = Glob('lib/**.tcmpp_event_config.json');

      // 合并配置
      config.forEach((key, value) {

      });

      log.info('[EventConfigAggregator] Merged config from ${input.path}: ${config.keys.join(", ")}');
    } catch (e) {

    log.info('[EventConfigAggregator] Generated unified config with ${allConfigs.length} entries');
  } else {
