Flutter 不更新启动器图标

Question

I created a new icon for my app and I used flutter launcher icons for generate the launcher icon. In the midmap folders there is the ic_launcher.png and if I open it is my new launcher icon. But if I install the app via android studio on my phone it shows the old icon.

It happened to me even when I created the first icon. It went all well but the app had the default flutter icon. It started to show the new one when I changed the app name but now I cannot change it again.

I already tried with the flutter-launcher-icons widget, to use flutter clean, ecc... but it doesn't change. Why there is this problem? And where the app takes the old logo information?

UPDATE

I discovered a workaround for this problem. If I delete all generated files (even the ones that looks right) and then I regenerate them when I install the app on the phone the icon looks right.

Answer 1

There will be 5 different mipmap files within android/app/src/res/main folder. Each mipmap consists icon launcher of different dimensions and pixels. Make sure you have replaced all 5 icon launchers with your generated Icon Launcher.

You can Generate Icon Launcher from here .

I've had a similar problem, where the app icon would always be the androids default one. The way I fixed this, was by looking at the following Github thread: https://github.com/flutter/flutter/issues/59305

I noticed, that there was an error in my AndroidManifest.xml, where the android:icon="@mipmap/launcher_icon" was not inside the application-tag. After placing the ">" after android:icon="@mipmap/launcher_icon", it worked for me.
