Flutter 在mixin中使用setState

• 相关问题

创建mixin

import ‘package:flutter/material.dart‘;

mixin JobsMixin<T extends StatefulWidget> on State<T> {
  @override
  void initState() {
    super.initState();
  }

  int page = 1;
  bool isLoading = false;
  List<JobData> jobs = [];

  Future<List<JobData>> getJobs(String city, [String searchValue = ‘‘]) async {
   // ...
  }

  loadMoreJobs(String city, [String searchValue = ‘‘]) async {
   // ...
  }
}

使用

class SearchView extends StatefulWidget {
  @override
  _SearchViewState createState() => _SearchViewState();
}

class _SearchViewState extends State<SearchView> with JobsMixin<SearchView> {
 // ...
}

class JobsTab extends StatefulWidget {
  @override
  JobsTabState createState() => JobsTabState();
}

class JobsTabState extends State<JobsTab> with JobsMixin<JobsTab> {
 // ...
}
