如何移除Flutter TabBar点击或切换时的Ripple（波纹）效果

要彻底消除TabBar的点击波纹，你需要补充设置TabBar的overlayColor属性，同时保留已有的splashFactory配置，具体修改如下：

修改后的完整代码 #

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

void main() => runApp(
      MaterialApp(
        title: "App",
        home: Sample(),
      ),
    );

class Sample extends StatefulWidget {
  @override
  _StackOverState createState() => _StackOverState();
}

class _StackOverState extends State<Sample> with SingleTickerProviderStateMixin {
  late TabController _tabController;

  @override
  void initState() {
    _tabController = TabController(length: 2, vsync: this);
    super.initState();
  }

  @override
  void dispose() {
    _tabController.dispose();
    super.dispose();
  }

  final yourTheme = ThemeData.light();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Tab bar'),
      ),
      body: Theme(
        data: yourTheme.copyWith(
          highlightColor: Colors.transparent,
          splashColor: Colors.transparent,
          splashFactory: NoSplash.splashFactory,
        ),
        child: Column(
          children: [
            Container(
              width: MediaQuery.of(context).size.width / 2,
              height: 45,
              decoration: BoxDecoration(
                color: Colors.blue,
                borderRadius: BorderRadius.circular(25.0),
              ),
              child: Container(
                color: Colors.transparent,
                child: TabBar(
                  splashFactory: NoSplash.splashFactory,
                  // 新增：移除点击反馈的overlay颜色
                  overlayColor: MaterialStateProperty.all(Colors.transparent),
                  labelPadding: EdgeInsets.zero,
                  controller: _tabController,
                  indicator: BoxDecoration(
                    borderRadius: BorderRadius.circular(25.0),
                    color: Colors.green,
                  ),
                  indicatorColor: Colors.transparent,
                  dividerColor: Colors.transparent,
                  labelColor: Colors.white,
                  unselectedLabelColor: Colors.black,
                  tabs: [
                    Tab(
                      child: Align(
                        alignment: Alignment.center,
                        child: Text("Place Bid"),
                      ),
                    ),
                    Tab(
                      child: Align(
                        alignment: Alignment.center,
                        child: Text("buy now"),
                      ),
                    ),
                  ],
                ),
              ),
            ),
            Expanded(
              child: TabBarView(
                controller: _tabController,
                children: [
                  Center(
                    child: Text(
                      'Place Bid',
                      style: TextStyle(
                        fontSize: 25,
                        fontWeight: FontWeight.w600,
                      ),
                    ),
                  ),
                  Center(
                    child: Text(
                      'Buy Now',
                      style: TextStyle(
                        fontSize: 25,
                        fontWeight: FontWeight.w600,
                      ),
                    ),
                  ),
                ],
              ),
            ),
          ],
        ),
      ),
    );
  }
}

关键修改说明 #

1. 添加overlayColor属性：Flutter 2.0及以上版本中，组件的点击反馈（包括波纹）主要由overlayColor控制，设置为透明后会直接移除点击时的波纹效果。
2. 保留splashFactory: NoSplash.splashFactory：确保彻底禁用所有类型的波纹渲染逻辑。
3. 精简冗余代码：移除了Tab中不必要的Container嵌套，保持代码简洁。
