Flutter 启动器图标没有改变？

Question

Am new to Flutter. I gone through the flutter documentation and followed the steps to configure custom launcher icons for my flutter project but app Launcher icon is not getting changed? Not sure what am missing.

Code:

dev_dependencies:
  flutter_test:
    sdk: flutter  
  flutter_launcher_icons: "^0.7.0"

flutter_icons:
  image_path: "icon/icon.png"
  android: true 
  ios: true

Answer 1

您必须获取包，然后运行以下命令来更改图标。

 $ flutter pub pub run flutter_launcher_icons:main

Answer 2

1. Add flutter_launcher_icons: ^0.7.3 code Plugin to pubspec.yaml

2. in pubspec.yaml :

    flutter_icons: image_path_android: "images/logoapp.png" image_path_ios: "images/logoapp.png" android: true ios: true

3. run command : flutter pub get

4. run command : flutter pub pub run flutter_launcher_icons:main

5. run command : flutter clean

6. run command : flutter run

it worked for me

Answer 3

4. Launcher Icons I generated using external website https://romannurik.github.io/AndroidAssetStudio/icons-launcher.html

Answer 4

there is two way to update app icon

1) first way

dev_dependencies:
  flutter_test:
    sdk: flutter  

  flutter_launcher_icons: "^0.7.5"

flutter_icons:
  image_path: "icon/appicon.png"
  android: true 
  ios: true

run this two command

flutter pub get

flutter pub run flutter_launcher_icons:main

2) if above not work then below solutions (change in native)

you can change appicon from Image Asset, right click on main folder of your project structure and go new -> Image Asset , now just select your icon and finish it, Android studio will generate all necessary icons for you.

similarly you can change appicon for ios, go

ios -> Runner -> Assets.xcassets -> Appicon.appiconset

then replace icons with your new icons

that's it!

Answer 5

I wasn't using flutter_launcher_icons , I was using just Image Asset Studio in the Android project. It seemed that in certain situations it wasn't updating my Adaptive Icon on Android.

To fix it, I opened the Android module (right click on the android/ folder in the Flutter view, then select Flutter | Open Android Module in Android Studio). From there, open the res/ folder and delete everything that looks like foreground.xml . AFAICT this is what is generated by Image Asset Studio as part of the Adaptive Icon.

Then recreate the Adaptive Icon via Image Asset Studio.

At this point my Flutter cache was corrupted, so I had to run flutter pub cache repair (I mention this because maybe somehow that is what fixed it, but I doubt it). Run the app and then voila, the icon updated.

Answer 6

For me the folder drawable-v24 was a problem. After removing foreground.xml from there it worked.

Answer 7

First add flutter_launcher_icons: ^0.8.1 code Plugin to pubspec.yaml

in pubspec.yaml file:

1. flutter_icons: image_path_android:"images/logoapp.png" image_path_ios:"images/logoapp.png" android:true ios:true

2. check iOS -Folder -> Runner -> Assets.xcassets -> AppIcon.appiconset: if duplicates exist delete them.

run commands : flutter pub get run commands : flutter pub pub run flutter_launcher_icons:main run commands : flutter clean run commands : flutter run

This worked for me.

Answer 8

For anyone getting any errors when they try to run flutter pub pub run flutter_launcher_icons:main , you may have not added Flutter to PATH. Follow this answer here to add Flutter to Path.

Answer 9

Those who had faced problems in changing the flutter icon in VS code, go to android/app/build.gradle. Then change the value of the following two properties:

// minSdkVersion 26
// targetSdkVersion 30

Then the same process.

Answer 10

I realized that there is a Contents.json file under ios/Runner/Assets.xcassets/AppIcon.appiconset that contains the name of the previous png files, which didn't match the new files that was replaced in that folder.

I properly updated the json file with the new file names, then removed the application on my simulator and run the build again. Then I could see the new icon on ios.

Answer 11

Just run the following flutter_launcher_icon and then run your app.

Answer 12

If you have flavors in IOS,

Goto Xcode > Runner > Build Settings > Asset Catalog Compiler - options > Primary App Icon Set Name and add values for each flavor
