Android Developers: Building reliable text editing experiences in Compose

The journey to reliable text editing in Compose culminated in the complete rewrite of BasicTextField. This shift to a buffer-driven architecture eliminated IME race conditions once and for all. This session unpacks why legacy input syncing had to go and how TextFieldState keeps keyboard updates in sync. From there, take a deep dive into formatted editing to explore the mechanics of TrackedRange, the performance costs of edit blocks, and the real-world catches behind style boundaries, before taking an early peek at Markdown rendering.
