如何为我的 Flutter Web 应用程序配置图标？
我正在尝试使用 flutter for web，但找不到如何配置图标的信息。
这应该是可能的，因为taphero_web以某种方式做到了。我查看了他们的来源，但找不到他们为该网站提供的图片：
我使用 codemagic.io 托管我的应用程序。有任何想法吗？

Glad you ask! As the owner of that project I can tell you how I did it:
UPDATE: With PWA support and Flutter 2
1- Inside your /web folder (to be pushed to the server), add a /icons folder (if your don't have it already).
2- Once you're there, you need to upload your set of images with websites like this one.
3- Is going to look something like this:
4- You should have a manifest.json and is going to look something like this:
{
"name": "Tap Hero",
"short_name": "Tap Hero",
"start_url": ".",
"display": "standalone",
"background_color": "#000000", // any HEX color works
"theme_color": "#000000", // any HEX color works
"description": "anything you want here",
"orientation": "portrait" // or changed as you wish
"prefer_related_application": false,
"icons": [
{
"src": "\/icons/android-icon-36x36.png",
"sizes": "36x36",
"type": "image\/png",
"density": "0.75"
},
{
"src": "\/icons/android-icon-48x48.png",
"sizes": "48x48",
"type": "image\/png",
"density": "1.0"
},
{
"src": "\/icons/android-icon-72x72.png",
"sizes": "72x72",
"type": "image\/png",
"density": "1.5"
},
{
"src": "\/icons/android-icon-96x96.png",
"sizes": "96x96",
"type": "image\/png",
"density": "2.0"
},
{
"src": "\/icons/android-icon-144x144.png",
"sizes": "144x144",
"type": "image\/png",
"density": "3.0"
},
{
"src": "\/icons/android-icon-192x192.png",
"sizes": "192x192",
"type": "image\/png",
"density": "4.0"
}
]
}
5- Once you did all that, add the rest of the icons inside your index.html:

- IF (by any chance) your
/weband ormanifest.jsonfiles are corrupted/broken/etc you can delete the entire file and do "flutter create ." that will generate everything again for you and can do a new try every single time.
- 是的，我使用了我在此处发布的资产链接（“这个”）：https://www.favicon-generator.org/“要推送到服务器的文件夹”是保存您的 index.html 的文件夹，等在执行 webdev 构建后生成的 (3认同)

我开始按照 Mariano Zorilla 的回答中的说明进行操作，但发现如果您只想为 Flutter Web App 设置 Favicon，它会简单得多。
- 在像 Mariano 建议的那样的图标创建网站中上传您的图像。
选择“仅生成 16x16 favicon.ico”选项并下载图标文件。
在
web/文件夹中，用favicon.png新生成的favicon.ico文件替换默认的颤振在
web/index.html文件中，
代替：
<link rel="shortcut icon" type="image/png" href="favicon.png"/>
和：
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon">
<link rel="icon" href="favicon.ico" type="image/x-icon">
- 使用此解决方案，“将图标保存到主屏幕”是否有效？或者只是在地址栏上显示一个小图标？ (3认同)
要为 flutter web 配置您的网站图标，只需将路径中的文件替换为./web/favicon.png您自己的图标，然后运行flutter build web.
- 只是想强调香蕉说的话。如果 Flutter 应用程序当前正在运行，请确保重建该应用程序。我已经运行了应用程序并进行了更改，但刷新后没有任何反应 (5认同)
