json全局转换器未生效

[54cz]

发现只有注解上的转换器有效果 @JsonSerializable(genericArgumentFactories: true, converters: [SafeNumConverter()])

以下全局的转换器并没有产生作用？
json_annotation:
options:
# 启用全局转换器
converters:
- 'package:flutter_module/lib/core/jsonConverter/safe_dateTime_converter.dart::SafeDateTimeConverter'
- 'package:flutter_module/lib/core/jsonConverter/safe_num_converter.dart::SafeNumConverter'
- 'package:flutter_module/lib/core/jsonConverter/safe_map_converter.dart::SafeMapConverter'
- 'package:flutter_module/lib/core/jsonConverter/safe_list_converter.dart::SafeListConverter'
