如何在使用 "CarouselSlider" 时根据移动设备大小调整图像大小，并在抖动中将按钮文本放在该图像上？

Question

我正在尝试为我的应用程序创建简介演练滑块，但我无法正确执行操作。使用 pub.dev 提供的 carousel_slider。我无法将图像填充到整个手机屏幕。它在左侧和右侧都留有一些空白 space 。

使用 Carousel Pro 我无法在滑动图像上放置按钮或文本。我在一些小问题上花了几个小时，但无法实现我想要的。

这是代码

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


void main() {
  runApp(MaterialApp(
    home: MyApp(), // Making initializing home sceen
  ));
}

List<String> imgList = [
  "lib/assets/images/sunset.jpg",
  "lib/assets/images/sample3.jpg",
  "lib/assets/images/sample2.jpg",
  "lib/assets/images/sunshine.jpg",
  "lib/assets/images/leaf.png",


];
int current = 0;

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  // var _userName = TextEditingController();

  @override
  Widget build(BuildContext context) {
    Container(
              child: ImageCarousel(),
            );
}


class ImageCarousel extends StatefulWidget {
  @override
  _ImageCarouselState createState() => _ImageCarouselState();
}

class _ImageCarouselState extends State<ImageCarousel> {
  @override
  Widget build(BuildContext context) {

// >>>>>>>>>>>>  C A R O U S E L    S L I D E R    C O D E

    return CarouselSlider(
      height: double.infinity,
      initialPage: 0,
      enableInfiniteScroll: false,
      onPageChanged: (index) {
        setState(() {
          current = index;
        });
      },
      items: imgList.map((imgUrl) {
        return Builder(
          builder: (BuildContext context) {
            return Container(
              //width: MediaQuery.of(context).size.width,
              width: double.infinity,
              margin: EdgeInsets.symmetric(horizontal: 1),
              decoration: BoxDecoration(
                color: Colors.green,
              ),
              child: Image(
                image: AssetImage(
                  imgUrl,
                ),
                fit: BoxFit.cover,
              ),
            );
          },
        );
      }).toList(),
    );
  }
}

  @override
  _ImageCarouselState createState() => _ImageCarouselState();
}

class _ImageCarouselState extends State<ImageCarousel> {
  @override
  Widget build(BuildContext context) {
    return Carousel(
          images: [

          AssetImage("lib/assets/images/sample3.jpg"),
        ]
    );

顺便说一句，我已经在 pubspec.yaml.

中安装了所有软件包和图像

对于 carousel_slider 来填充整个页面集：viewportFraction: 1.0

要将内容放在图像创建堆栈的顶部：

CarouselSlider(
          height: double.infinity,
          viewportFraction: 1.0,
          initialPage: 0,
          enableInfiniteScroll: false,
          items: imgList.map((imgUrl) {
            return Stack(
              children: <Widget>[
                Image(
                  height: double.infinity,
                  image: NetworkImage(
                    imgUrl,
                  ),
                  fit: BoxFit.cover,
                ),
                Text("TEST")
              ],
            );
          }).toList(),
        ))
