Migrate View modules from Java to Kotlin

[OneXeor]

Description

All View modules are written in Java. Migrate to Kotlin for consistency with modern Android development and the Compose module.

Tasks

• Convert ParticlesView.java → ParticlesView.kt
• Convert DotItem.java → DotItem.kt
• Convert ParticleProgressBar.java → ParticleProgressBar.kt
• Convert Ball.java → Ball.kt
• Convert PulseButton.java → PulseButton.kt
• Convert BottomNavigationBar.java → BottomNavigationBar.kt
• Convert CenterNavigationButton.java → CenterNavigationButton.kt
• Convert demo app MainActivity.java → MainActivity.kt
• Update build.gradle files with Kotlin plugin

Benefits

• Null safety
• Concise syntax
• Coroutines support for animations
• Consistency with Compose module
• Modern Android standard

Hi @OneXeor 👋
Is this task currently available for contributors to work on?
If yes, I can start and submit the migration in small phases (file-by-file). Thanks!

Hey @OneXeor 🙌 thanks bro!
I can take this up ✅ I’m comfortable with Android + Kotlin migrations.
I’ll do the migration file-by-file in small PRs (ParticlesView → DotItem → ProgressBar → PulseButton → BottomNav → Demo app) so it’s easy to review and safe to merge.

Quick confirmation: do you want the Kotlin conversion to be purely mechanical (Android Studio converter) or should I make it idiomatic Kotlin (null-safety, properties, cleanup) while keeping the public API stable?

Also before I invest a lot of time — is this task paid/sponsored (bounty/contract) or it’s a pure open-source contribution?
Either way I’m happy to help ✅🙂 just want to plan my time properly.

Small update @OneXeor 🙌✅: I’ll migrate DotItem.java → DotItem.kt first since it’s a dependency for ParticlesView, then I’ll move to ParticlesView.java → ParticlesView.kt.
This way the PRs stay clean, easy to review, and safe to merge.

It should be made in idiomatic way 🙃

Unfortunately there is no any bounty/contract.
