Message class

消息记录。WS im.message 的 from_id/to_from_id/talk_mode 只在外层 payload。

Constructors

Message({String msgId = '', String sequence = '0', int msgType = MsgType.text, int fromId = 0, String nickname = '', String avatar = '', int isRevoked = YesNo.no, String sendTime = '', Map<String, dynamic>? extra, Map<String, dynamic>? quote, int talkMode = TalkMode.private, int toFromId = 0, int status = 0})
Message.fromJson(Map<String, dynamic> json)
factory
Message.fromPushPayload(Map<String, dynamic> payload)
从 WS im.message 推送帧构建 Message。 from_id / to_from_id / talk_mode 只读外层 payload。

fromId ↔ int
getter/setter pair
hashCode → int
The hash code for this object.

sendTime ↔ String
getter/setter pair
seq → int
将 sequence 解析为整数（仅用于本地排序/比较，非独立字段）
no setter
sequence ↔ String

status ↔ int
本地发送状态：0 成功/已收，1 发送中，2 失败

Methods

copyWith({String? msgId, String? sequence, int? msgType, int? fromId, String? nickname, String? avatar, int? isRevoked, String? sendTime, Map<String, dynamic>? extra, Map<String, dynamic>? quote, int? talkMode, int? toFromId, int? status}) → Message
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>
toStorageMap({required int ownerId}) → Map<String, dynamic>
落库用扁平 Map（sequence 以整数写入，保证本地排序/比较与服务端一致）
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
inherited

Static Methods

compareNewestFirst(Message a, Message b) → int
最新在前（sequence desc, send_time desc） seq<=0 的未同步消息视为最新（避免 AI 落库暂无 seq 时被排到列表顶部「消失」）
compareOldestFirst(Message a, Message b) → int
最旧在前（UI 列表：旧→新） seq<=0 排在已同步消息之后（底部），避免打字机结束后气泡「消失」
dedupeByMsgId(Iterable<Message> list) → List<Message>
同 msg_id 保留 sequence 更大的
