Flutter 本地通知图标未显示 [英] Flutter local notifications Icon not showing

问题描述

我遇到了一个很常见的问题，但我看到的任何解决方案都没有帮助我.所以，我正在尝试显示本地通知.

I am facing a problem that is very common, but no solution I saw helped me. So, I'm trying to show local notifications.

除了图标外，一切正常.按照包的文档，我向可绘制对象添加了一个图标，但它不起作用.

Everything works except the icon. Following the package's documentation, I added an icon to the drawable, but it doesn't work.

这是我的文件夹结构和我想显示的图像

Here is the structure of my folder and the image I want to show

这是我的初始化代码

我尝试了很多东西.我创建了透明的图标(使用 https://romannurik.github.io/AndroidAssetStudio/)和添加到可绘制对象中，添加了第一个图像中的 PNG.

I tried many things. I created icons with transparency (using https://romannurik.github.io/AndroidAssetStudio/) and added to the drawable, added the PNG as in the first image.

它仅在我将标准图标复制到可绘制对象(即 Flutter 徽标)时才有效.

It only works when I copy the standard icon to the drawable, which is the Flutter logo.

推荐答案

这个包的文档不是很清楚.您需要将 app_icon 名称更改为 res/drawable 文件夹中的图标文件，才能使自定义图标生效.在您的情况下，一个示例可以是 ic_launcher.png.代码中用于更改的特定行是:

Documentation of this package is not so clear about it. You need to change name app_icon to the icon file from your res/drawable folder to have an effect of your custom icon. In your case one example can be ic_launcher.png. Specific line in your code for a change is:

const AndroidInitializationSettings initializationSettingsAndroid =
    AndroidInitializationSettings('app_icon');
