To solve this, Apple has introduced Swift for iOS, and Google has adopted Kotlin for Android. To select these newer languages when creating an app, enter this command into your terminal:

flutter create \
--ios-language swift \
--android-language kotlin \

Flutter will now create platform shells that use Swift and Kotlin. If you don't specify anything, Objective-C and Java will be chosen. You are also never locked into this decision. If later down the road you want to add some Kotlin or Swift code, there is nothing stopping you from doing so.
