tabs切换

简单的tabs切换

// view
Widget _buildTab() {
  return TDTabBar(
    controller: controller.tabController,
    tabs: controller.tabNames.map((e) => TDTab(text: e)).toList(),
    onTap: (index) => controller.onTapTabItem(index),
    backgroundColor: Colors.white,
    showIndicator: true,
    indicatorColor: const Color(0xffe01e1e),
    labelColor: const Color(0xffe01e1e),
  );
}


// controller
import 'package:flutter/material.dart';
import 'package:get/get.dart';
class OrderDetailController extends GetxController with GetTickerProviderStateMixin {
  OrderDetailController();
  // tab 控制器
  late TabController tabController;
  // tab 索引
  int tabIndex = 0;
  // tab 名称
  List<String> tabNames = ['全部', '待付款', '待发货', '待收货', '已完成'];
  void onTapTabItem(int index) {
    tabIndex = index;
    print('tabIndex: $tabIndex');
    update(["order_detail"]);
  }
  
  @override
  void onInit() {
    super.onInit();
    tabController = TabController(length: tabNames.length, vsync: this);
  }

  @override
  void onClose() {
    super.onClose();
    tabController.dispose();
  }
}

tabs切换和视图同步

// view
Widget _buildView() {
  return <Widget>[
    _buildTab(),
    Expanded(
      child: TabBarView(
        controller: controller.tabController,
        children: const [
          Center(child: Text('内容1')),
          Center(child: Text('内容2')),
          Center(child: Text('内容3')),
          Center(child: Text('内容4')),
          Center(child: Text('内容5')),
        ],
      ),
  ),
  ].toColumn();
}
