feat: support for Gradle Kotlin DSL (Kotlin DSL comes as standard in newly created Flutter projects)

[devNamanG]

fixes #305
fixes #374

Description

Added support for updating android/build.gradle.kts, android/settings.gradle.kts and android/app/build.gradle.kts files.
Added RegExps, functions to handle Kotlin Gradle DSL files if Groovy Gradle DSL files are not found
We assume that the project does not use a mix of Groovy and Kotlin DSL gradle files.
We check whether the android/build.gradle file exists or not. If it exists, the existing code handles updating the files.
If it does not not exist, we proceed to check whether android/build.gradle.kts file exists.
If it does, we use Kotlin DSL configuration.
If both configuration files are not found, an Exception is thrown.

Okay so I tried running the code on a project with Kotlin DSL files, and for some reason, it is not updating the those files, even though it does write google-services.json. Can someone check this out as well? The existing plugin code seems to not even call the updated gradleContentUpdates function. It would be really helpful if a maintainer checks this out, thank you!

Has this been implemented? Still having this issue with my app even with latest dev build.

Hey @Henry5775 , no i don't think so, last i checked this was still not working. Then I just abandoned using Kotlin DSL and switched to Groovy DSL instead.

Same here. Wasted so much time trying to find a solution to this.

Tests will probably fail as there's a token required which isn't available for forked PRs, I ran locally and they all passed
