While developing a Flutter project in Android Studio, I got the following message:
Multiple arb files with the same ‘en’ locale detected.
Ensure that there is exactly one arb file for each locale.
This project is having problems with localization.
‘intl_en.arb’ is newly generated.
When I deleted intl_en.arb,
flutter –no-color pub global run intl_utils:generate
I had intl_utils installed without realizing it.
It automatically generates boilerplate code for Intl, the official Dart localization library.
The function of Intl_utils is provided as Plugin “Flutter Intl” of Android Studio.
When I checked, I found that I was using Flutter Intl, a Plugin for Android Studio.
In this project, the localization process was already set according to the following article in the Flutter official documentation.
So, I decided to stop Flutter Intl this time.
Android Studio > Settings… > Plugins > Uncheck Flutter Intl
This solved the ‘Multiple arb files with the same ‘en’ locale detected.’ issue
