我有一个网页,需要2个不同的APIC电话。

我正在运用清洁结构来撰写该守则,并将之作为国家管理。 然后,我利用自由套线绘制各州地图。

How can I combine the different states? What I would like to achieve is to emit a success state only if both states give me data or emit an error state if one of them is an error, otherwise loading state.

提前感谢。

它们是:

import  package:freezed_annotation/freezed_annotation.dart ;
import  ...eatures/profile/domain/entities/user_profile_entity.dart ;

part  user_profile_details_state.freezed.dart ;

@freezed
class UserProfileDetailsState with _$UserProfileDetailsState {
  ///Initial
  const factory UserProfileDetailsState.initial() =
      _UserProfileDetailsStateInitial;

  ///Loading
  const factory UserProfileDetailsState.loading() =
      _UserProfileDetailsStateLoading;

  ///Data
  const factory UserProfileDetailsState.data(
      {required ProfileEntity profileEntity}) = _UserProfileDetailsStateData;

  ///Error
  const factory UserProfileDetailsState.error([String? error]) =
      _UserProfileDetailsStateError;
}

import  package:freezed_annotation/freezed_annotation.dart ;
import  ....features/profile/domain/entities/user_properties_entity.dart ;

part  user_properties_state.freezed.dart ;

@freezed
class UserPropertiesState with _$UserPropertiesState {
  ///Initial
  const factory UserPropertiesState.initial() = _UserPropertiesStateInitial;

  ///Loading
  const factory UserPropertiesState.loading() = _UserPropertiesStateLoading;

  ///Data
  const factory UserPropertiesState.data(
          {required UserPropertiesEntity userPropertiesEntity}) =
      _UserPropertiesStateData;

  ///Error
  const factory UserPropertiesState.error([String? error]) =
      _UserPropertiesStateError;
}

这些是两个通知人:
