KotlinPoet with Egor Andreevich

The Developers' Bakery

Let’s kickoff 2025 with a fresh new episode of The Developers’ Bakery! 🎉

Today, we talk about KotlinPoet with Egor Andreevich. KotlinPoet is a library from Square used to generate Kotlin code. It’s a great tool to generate code at compile time, and it’s used by many libraries and frameworks for Android and not only.

Egor has been involved with KotlinPoet for multiple years and today will share with us how KotlinPoet works, when to use it, and how to contribute to the project.

Enjoy the show 👨‍🍳
