How to Change Your Flutter App Icon

Are you tired of using the same old icon for your Flutter app? Do you want to give your app a fresh new look? Look no further! In this article, we will guide you through the process of changing your Flutter app icon.

Preparing Your Icons

Before you start, make sure you have all the necessary icons ready. For Android apps, use an image with transparent edges and save it as `ic_launcher_xxxhdpi.png` in the `assets/icon/` directory. For iOS apps, save a single icon as `ios.png` in the same directory.

Configuring Your Icons

To configure your icons for both Android and iOS, you will need to use the `FlutterDynamicIcon` plugin. This plugin allows you to dynamically change your app's icon and icon batch number.

First, add the `flutter_dynamic_icon` plugin as a dependency in your `pubspec.yaml` file. Then, import the plugin in your Dart code using the following line:

```dart

import 'package:flutter_dynamic_icon/flutter_dynamic_icon.dart';

```

Using the Plugin

To use the plugin, you will need to set the alternate icon name with the `CFBundleAlternateIcons` key as an argument. Here's how to do it:

```dart

await FlutterDynamicIcon.Flutter_icons(

android: true,

ios: true,

image_path_android: 'assets/icon/ic_launcher_xxxhdpi.png',

image_path_ios: 'assets/icon/ios.png',

adaptive_icon_background: 'assets/icon/ic_background.png',

adaptive_icon_foreground: 'assets/icon/ic_foreground.png',

);

```

Additional Tips

* Make sure to set the `CFBundleIcons` dictionary for iPads as well.

* If you don't plan on using the UINewsstandIcon, erase it or your app may get rejected upon submission to the App Store.

* Set three dictionaries under `CFBundleAlternateIcons` corresponding to teamfortress, photos, and chills.

* Add `CFBundleAlternateIcons` as a dictionary and use it for alternative icons.

Troubleshooting

If you encounter errors when uploading your build to the App Store, make sure to select 'create folder references' or 'create groups' when copying files to Xcode. Also, keep in mind that these icons should not be kept in the `Assets.xcassets` folder but outside of it.

By following these simple steps, you can easily change your Flutter app icon and give your app a fresh new look. Happy coding!
