Recreate Flutter's ios and android folder with Swift and Kotlin

Question

Hi I just found out that it is possible to create Flutter project with Swift and Kotlin. However, I'm already invested in my current projects and want to recreate the ios and android as Swift and Kotlin (currently they are default to Java and ObjC).

Thanks.

Answer 1

use -i and -a to create new project, like this:

flutter create -i swift -a kotlin project_name

see also:https://docs.flutter.dev/development/platform-integration/platform-channels#example-project then replace with lib folder from old project.

swift and kotlin are default now. you can use those command to update exist project:

cd project
flutter create .

this command will update your project. then you can merge you old code into new project, and remove old code.
make sure you backup your project before run it, and you know what are you exactly doing

Answer 2

You can also run flutter create -i swift . inside your app folder, to regenerate ios folder.

I've not tested android, but I guess the same should work for it too - flutter create -a kotlin .

Answer 3

I just deleted default ios and android folder in my flutter project. now in order to generate these default folder again you can use this below command :

flutter create .

Note : "." is also part of command , also make sure that your project folder name should not contain spaces or special characters which are invalid for package name.
