May 1, 2026

May 2026: Three targeted improvements delivering long-term business value in Flutter. PlatformViewCreationRequest: enforced static factory usage by making the primary constructor private and requiring explicit static factories, preserving testing contracts and improving maintainability. Android templates: added explicit tests to ensure Gradle/AGP/KGP/Java dependency versions stay within supported ranges, preventing regressions and noisy warnings. MotionEvent-JNI logs: filtered spammy log messages to reduce noise and improve developer focus. No major bugs fixed this month; primary value came from structural improvements, better testing coverage, and cleaner logs.
