底部导航栏在颤动中溢出

Question

这是我的代码。准确地说，底部导航栏溢出了 12 和 26 像素。有解决办法吗？ ** 尝试了各种方法。我还创建了自定义底部导航栏小部件并将其放置在扩展小部件下方。我收到同样的错误（溢出值不同）。现在，我正在使用一个名为 ScrollBottomNavigationBar 的 flutter 包。

import 'package:flutter/material.dart';
import 'package:justchat/components/bottom_navigation_bar.dart';
import 'package:justchat/components/input_box.dart';
import 'package:justchat/constants.dart';
import 'package:justchat/screens/login_screen.dart';
import 'package:scroll_bottom_navigation_bar/scroll_bottom_navigation_bar.dart';

class HomeScreen extends StatelessWidget {
  final controller = ScrollController();
  final items = <BottomNavigationBarItem>[
    BottomNavigationBarItem(
      icon: Icon(
        Icons.home,
        size: 10,
      ),
      label: ("Home"),
    ),
    BottomNavigationBarItem(
      icon: Icon(
        Icons.settings,
      ),
      label: ("Settings"),
    ),
  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      bottomNavigationBar: ClipRRect(
        borderRadius: BorderRadius.only(
          topRight: Radius.circular(30),
          topLeft: Radius.circular(30),
        ),
        child: Wrap(
          children: [
            ScrollBottomNavigationBar(
              controller: controller,
              items: items,
            ),
          ],
        ),
      ),
      body: SafeArea(
        // bottom: false,
        child: Column(
          children: [
            Row(

                Padding(

只需使用Wrap Widget扭曲您的 BottomNavigationBar 即可。
