无法正常运行 null 安全

Question

在这里，当我运行代码时，它给了我这个问题......

错误的图片

这是我的依赖。

 # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  # carousel_slider: ^2.3.1
  cupertino_icons: ^1.0.2
  carousel_slider: ^2.3.1
  http: ^0.13.3
  get: ^4.3.8
  firebase_auth: ^3.1.1
  cloud_firestore: ^2.5.3
  firebase_core: ^1.6.0
  google_sign_in: ^5.2.1
  flutter_local_notifications: ^9.0.2
  firebase_messaging: ^11.0.0
  # google_maps_flutter: ^2.1.0
  # location: ^4.3.0

它是代码，库的第一行给出了错误，或者说它是说取消发送导入

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

class HomeScreen extends StatelessWidget {

  const HomeScreen({Key? key}) : super(key: key);
@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ListView(
        children: [
          CarouselSlider(
            items: [
              //1st Image of Slider
              Container(
                decoration: BoxDecoration(
                  image: const DecorationImage(
                    image: NetworkImage("")
                ),
               ),
  }
}

谢谢你的帮助！

单击 main.dart 单击 Edit Configuration 然后在 Additional run args 列中写入 --no-sound-null-safety

或将旋转木马 slider 更新为

 carousel_slider: ^4.0.0
