在 BoxDecoration 图像上强制使用 ClipRRect

Question

我正在尝试使我的图像变圆，但作为背景。问题是，ClipRRect 没有做我认为应该做的事情。除了使用 Stack 之外，我还喜欢其他解决方案，因为那样的话，根据列调整图像大小会成为一个问题，因为图像比列大。非常感谢。

编辑：所以，我很抱歉大家。我的同事给我的图像似乎是无意中填充的，因此边框不起作用。目前，我和我的同事已经修复了图像，现在一切正常。我通过在合身时使用 BoxFit.fill 实现了这一点，所以如果有人偶然发现这一点，他们可能想尝试 Boxfit.first 来检查图像。

ClipRRect(

删除您的cliprect。 BorderRadius 的 DecoratedBox 足以实现这一点。

试试这个：

import 'package:flutter/material.dart';

final Color darkBlue = Color.fromARGB(255, 18, 32, 47);

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData.dark().copyWith(scaffoldBackgroundColor: darkBlue),
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Center(
          child: MyWidget(),
        ),
      ),
    );
  }
}

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: DecoratedBox(
        decoration: BoxDecoration(
          borderRadius: BorderRadius.circular(30),
          image: DecorationImage(
            image: AssetImage(
              'images/ic_blackbackground.png',
            ),
            fit: BoxFit.cover,
          ),
        ),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            Padding(
              padding: const EdgeInsets.only(
                top: 24,
                bottom: 16,
                left: 24,
              ),
              child: Text(
