I am developing a Flutter app right now and trying to change the Android app's icon to a .png image. On Android Studio, I get this error when I do File -> New -> Image Asset:
Any help with this?
In you pubspec.yaml file add this,
dev_dependencies:
flutter_test:
sdk: flutter
flutter_launcher_icons: "^0.6.1"
flutter_icons:
android: true
ios: "Example-Icon"
image_path: "assets/icon/icon.png"
image_path_android: "assets/icon/icon_android.png"
image_path_ios: "assets/icon/icon_ios.png"
adaptive_icon_background: "#FFFAFAFA"
adaptive_icon_foreground: "assets/icon/icon-foreground.png"

I am beginner in flutter, and I started learning from the very beginning of creating the application and immediately encountered a problem that I cannot solve only on android. When i create packages launcher_icon and native_splash, on ios everything works as it should, but on android at the splash screen all the time it gives me only the application icon and not default splash screen as in ios.
how could i fix it to work on android?
dev_dependencies:
flutter_test:
sdk: flutter
flutter_lints: ^2.0.0
flutter_launcher_icons: ^0.10.0
flutter_native_splash: ^2.2.7
flutter_icons:
android: true
ios: true
image_path: "assets/icon_anny.png"
min_sdk_android: 21
flutter_native_splash:
color: "#fafafa"
image: assets/splash_screen.png
color_dark: "#000000"
image_dark: assets/splash_screen_dark.png
android: true
ios: true
android_gravity: fill
ios_content_mode: scaleAspectFill
I managed to solve the problem, Android 12 has a different way of showing the splash screen. It is also necessary to open a new one flutter_native_splash.yaml and there are all the instructions and it works perfectly.
You should run a command line after adding parameters to pubspec.yaml:
flutter pub run flutter_native_splash:create
I just fixed this problem today go in your project and create a flutter_native_splash.yaml and follow the instructions on https://pub.dev/packages/flutter_native_splash.

How to change the app icon in Flutter using VS Code?
I am trying it again and again but it's not working. I've seen different methods online with no positive outcome.
You can make use of the flutter_launcher_icons: ^0.9.2 package
Create new folder named assets and a subfolder inside that named icon then make changes in your pubspec.yaml file like following:
dev_dependencies:
flutter_launcher_icons: "^0.9.2"
flutter_icons:
android: "launcher_icon"
ios: true
image_path: "assets/icon/icon.png"
Here the icon image should be icon.png and it will be stored in the path : assets/icon
now in terminal run
flutter pub get
for further info check this as reference. And this video might be helpful.
With the help of flutter plugin you may change flutter icon package:
flutter_launcher_icons: ^0.9.2
Step 1:
dev_dependencies:
flutter_launcher_icons: "^0.9.2"
flutter_icons:
android: "launcher_icon"
ios: true
image_path: "assets/icon/icon.png"
Step 2:
flutter pub get
Use current method Flutter Launcher Icons.
Edit pubspec.yaml file:
dev_dependencies:
flutter_launcher_icons: "^0.10.0"
flutter_icons:
android: "launcher_icon"
ios: true
image_path: "assets/icon/icon.png"
min_sdk_android: 21 # android min sdk min:16, default 21
web:
generate: true
image_path: "path/to/image.png"
background_color: "#hexcode"
theme_color: "#hexcode"
windows:
generate: true
image_path: "path/to/image.png"
icon_size: 48 # min:48, max:256, default: 48
Go to Terminal:
flutter pub get
flutter pub run flutter_launcher_icons:main
Have a nice day...

I created my first app. Not so big, news app. My dependencies:
provider: ^4.3.2+2
url_launcher: ^5.5.2
share: ^0.6.5+4
shared_preferences: ^0.5.10
flutter_html: ^1.0.2
cached_network_image: ^2.3.3
flutter_spinkit: "^4.1.2"
pull_to_refresh: ^1.6.3
sqflite: ^1.3.2+1
path_provider: ^1.6.24
connectivity: ^2.0.2

dio: ^3.0.10
hive: ^1.4.4+1
hive_flutter: ^0.3.1
scrollable_positioned_list: ^0.1.8
I will list app sizes in different cases:
flutter build apk => size around 25MB.
flutter build apk --split-per-abi => size around 10MB.
flutter build ios => size of Runner.app is 475MB (I'm not joking).
Ok I can compress it => size 203MB - This is
Ok, flutter I'll create a blank app
flutter build ios => size of Runner.app is 65MB and after compress 23 (this seems affordable).
I hope this will you
flutter clean
flutter build ios --analyze-size
After I Archived app with XCode and deployed to the App Store app size was only 45MB (shown on Console) and after download to actual device size was only 29 MB.
From 475 to 29MB. That was amazing!
I think this can be helpful to someone else, so don't worry about size...
