Error: Method not found: 'Observable.combineLatest2'

Question

编译器消息： lib/app/home/entries/entries_bloc.dart:17:62：错误：找不到方法：'Observable.combineLatest2'。 流> 获取 _allEntriesStream => Observable.combineLatest2( ^^^^^^^^^^^^^^^

Stream<List<EntryJob>> get _allEntriesStream => Observable.combineLatest2(
   database.entriesStream(),
   database.jobsStream(),
   _entriesJobsCombiner,
 );

Answer 1

改变这个：

Observable.combineLatest2(
   database.entriesStream(),
   database.jobsStream(),
   _entriesJobsCombiner,
 );

进入这个：

Rx.combineLatest2(
   database.entriesStream(),
   database.jobsStream(),
   _entriesJobsCombiner,
 );

Rx 实用程序 class 包含方法 combineLatest2
