添加依赖
dev_dependencies:
flutter_test:
sdk: flutter
build_runner: ^2.0.4
json_serializable: ^4.1.3
新建文件xxx_bean.dart
import 'package:json_annotation/json_annotation.dart';
part 'student_bean.g.dart';//这里需要写上报错先不管 等输入命令生成文件后会自动刷新
@JsonSerializable()
class XXX{
String? name;
int? age;
XXX({this.name, this.age});
factory XXX.fromJson(Map<String, dynamic> json) => _$XXXFromJson(json);
Map<String, dynamic> toJson() => _$XXXToJson(this);
}
pubspec.yaml路径下命令行输入
#生成命令
flutter packages pub run build_runner build
遇到冲突Conflicting outputs were detected and the build is unable to prompt for permission to 命令行输入下面两行 继续敲上面的生成命令
flutter packages pub run build_runner clean
flutter packages pub run build_runner build --delete-conflicting-outputs
