### :information_source: Info

Version: `0.10.0

### :speech_balloon: Description

idk why but it generates two '>>' isntead of one

C:\Development\flutter projects\pratura\android\app\src\debug\AndroidManifest.xml:11:9-43 Error:
Attribute application@icon value=(@mipmap/ic_launcher) from AndroidManifest.xml:11:9-43
is also present at AndroidManifest.xml:7:9-45 value=(@mipmap/launcher_icon).
Suggestion: add 'tools:replace="android:icon"' to element at AndroidManifest.xml:8:6-39:19 to override.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugMainManifest'.
> Manifest merger failed : Attribute application@icon value=(@mipmap/ic_launcher) from AndroidManifest.xml:11:9-43
is also present at AndroidManifest.xml:7:9-45 value=(@mipmap/launcher_icon).
Suggestion: add 'tools:replace="android:icon"' to element at AndroidManifest.xml:8:6-39:19 to override.

### :scroll: Pubspec.yaml

flutter_icons:
android: "launcher_icon"
ios: true
image_path: "assets/icons/logo.png"
min_sdk_android: 21 # android min sdk min:16, default 21
web:
generate: false
image_path: "path/to/image.png"
background_color: "#hexcode"
theme_color: "#hexcode"
windows:
generate: false
image_path: "path/to/image.png"
icon_size: 48 # min:48, max:256, default: 48

We ask that you include your pubspec.yaml file as a common problem we have seen has been the pubspec.yaml file being incorrect

Start with the generated android/app/src/debug/AndroidManifest.xml and the pubspec.yaml configuration shown in the report. Reproduce the processDebugMainManifest failure, then trace how the Android icon configuration is applied. Done means the manifest has one application icon source and the debug build completes without the merger error.
