When I create an app with a flutter create command, the flutter logo is used as an application icon for both platforms.
If I want to change the app icon, shall I go to both platforms directories and replace images there?, by platforms directories I mean myapp/ios/Runner/Assets.xcassets/AppIcon.appiconset for iOS and myapp/android/app/src/main/res for Android.
Or is it possible to define an image as a Flutter Asset and the icons are generated somehow?.

-- first go to :- https://www.appicon.co/ this website and generate your app logo. -- after that you got a two folder one android and second IOS. -- after that you can go this folder directory android -> app -> src -> main -> res then after you can replace all folder to generated new logo folder. after that it can been change in android app.
-- after that you can go this folder directory IOS -> runner and replace <Assets.xcassets> this folder to generated new logo folder. after that it can been changed in IOS app.
-- then after if you need change native screen image so follow this step. first go to IOS folder and press right class and open your project in x code. -- after that you can go in runner folder and move to assert image folder. -- after that you can see 1x, 2x and 3x image. -- you can change it new image according to 1x, 2x and 3x image.
-- after that you got a successfully change logo in both add with native scree.

Flutter has its own default icon for every app in its Android and Ios folder so there are few steps that I would like to show to change the app icon.

I use few methods for chaging flutter app lancher icon but only the manuall method is a bit easy and good. Because you will know how it work.
So to change flutter ios icon. First get copy of your icon 1024×1024 pixel and generate set of icons for android and ios using easyappicon generator. When you get zip file it work create two folder ios and android open ios folder and copy folder and replace the one in your ios/runner directory.
For android copy all folder present in android folder and replace the ones present in the android/app/src/main/res/drawable here.
After replacing folder on both ios and android stop the app and re run and your icons will be changed.

The flutter_launcher_icons package recommended in many answers above hasn't been updated for quite some time now and is throwing an uncaught exception.
You can use the package icons_launcher instead though.
dev_dependencies:
icons_launcher: ^1.1.7
flutter_icons:
image_path: 'assets/ic_logo_border.png'
ios: true
android: true
flutter pub get
flutter pub run icons_launcher:main
Without any packages
Android
Create an adaptive launcher icon in your Flutter project's root directory using the Android Asset Studio.
Add the generated launcher icon files to the project's android/app/src/main/res/mipmap-*/ directories.
Edit the android/app/src/main/AndroidManifest.xml file and add the following line below the tag:
<application android:icon="@mipmap/ic_launcher">
flutter build apk command to generate an APK with the new launcher icon.iOS
Create an Adaptive App Icon in your Flutter project's root directory using the App Icon Generator.
Add the generated app icon files to the project's ios/Runner/Assets.xcassets/AppIcon.appiconset/ directory.
Edit the ios/Runner/Info.plist file and add the following line below the tag:
<key>CFBundleIconName</key>
<string>AppIcon</string>
You have to replace the Flutter icon files with images of your own. This site will help you turn your png into launcher icons of various sizes:

Best way is to change launcher icons separately for both iOS and Android.
Change the icons in iOS and Android module separately. The plugin produces different size icons from the same icon which are distorted.

I was having some trouble using and understanding the flutter_launcher_icons package. This answer is how you would do it if you were creating an app for Android or iOS natively. It is pretty fast and easy once you have done it a few times.
Android launcher icons have both a foreground and a background layer.
(image adapted from Android documentation)
The easiest way to create launcher icons for Android is to use the Asset Studio that is available right in Android Studio. You don't even have to leave your Flutter project. (VS Code users, you might consider using Android Studio just for this step. It's really very convenient and it doesn't hurt to be familiar with another IDE.)
Right click on the android folder in the project outline. Go to New > Image Asset. (Try right clicking the android/app folder if you don't see Image Asset as an option. Also see the comments below for more suggestions.) Now you can select an image to create your launcher icon from.
Note: I usually use a
1024x1024pixel image but you should certainly use nothing smaller than512x512. If you are using Gimp or Inkscape, you should always have two layers, one for the foreground and one for the background. The foreground image should have transparent areas for the background layer to show through.
(lion clipart from here)
This will replace the current launcher icons. You can find the generated icons in the mipmap folders:
If you would prefer to create the launcher icons manually, see this answer for help.
Finally, make sure that the launcher icon name in the AndroidManifest is the same as what you called it above (ic_launcher by default):
application android:icon="@mipmap/ic_launcher"
Run the app in the emulator to confirm that the launcher icon was created successfully.
I always used to individually resize my iOS icons by hand, but if you have a Mac, there is a free app in the Mac App Store called Icon Set Creator. You give it an image (of at least 1024x1024 pixels) and it will spit out all the sizes that you need (plus the Contents.json file). Thanks to this answer for the suggestion.
iOS icons should not have any transparency. See more guidelines here.
After you have created the icon set, start Xcode (assuming you have a Mac) and use it to open the ios folder in your Flutter project. Then go to Runner > Assets.xcassets and delete the AppIcon item.
After that right-click and choose Import.... Choose the icon set that you just created.
That's it. Confirm that the icon was created by running the app in the simulator.
You can still create all of the images by hand. In your Flutter project go to ios/Runner/Assets.xcassets/AppIcon.appiconset.
The image sizes that you need are the multiplied sizes in the filename. For example, [email protected] would be 29 times 3, that is, 87 pixels square. You either need to keep the same icon names or edit the JSON file.

Best & Recommended way to set App Icon in Flutter.
I found one plugin to set app icon in flutter named flutter_launcher_icons. We can use this plugin to set the app icon in flutter.
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.2
flutter_launcher_icons: ^0.7.2+1**
Save the file and run flutter pub get on terminal.
Create a folder assets in the root of the project in folder assets also create a folder icon and place your app icon inside this folder. I will recommend to user 1024x1024 app icon size. I have placed app icon inside icon folder and now I have app icon path as assets/icon/icon.png
Now, in pubspec.yaml add the below code,
flutter_icons:
android: "launcher_icon"
ios: true
image_path: "assets/icon/icon.png"
flutter pub run flutter_launcher_icons:main -f pubspec.yaml
Then Run App
Flutter Launcher Icons has been designed to help quickly generate launcher icons for both Android and iOS: https://pub.dartlang.org/packages/flutter_launcher_icons
pubspec.yamlfile (within your Flutter project) to use itpubspec.yamlfile, specify the path of the icon you wish to use for the app and then choose whether you want to use the icon for the iOS app, Android app, or both.I'm hoping to add a video to the GitHub README to demonstrate the above.
A video showing how to run the tool can be found here.
If anyone wants to suggest improvements/report bugs, please add it as an issue on the GitHub project.
Update: As of Wednesday 24th January 2018, you should be able to create new icons without overriding the old existing launcher icons in your Flutter project.
Update 2: As of v0.4.0 (8th June 2018) you can specify one image for your Android icon and a separate image for your iOS icon.
Update 3: As of v0.5.2 (20th June 2018) you can now add adaptive launcher icons for the Android app of your Flutter project
