+# JNI callbacks invoked by maplibre_gl's native WindParticleHost.
+# R8 cannot see these calls because they originate in C++: without this rule a
+# release build renames or drops all four, GetMethodID fails, and opening a
+# wind layer crashes with NoSuchMethodError. Debug builds are not shrunk, so
+# only a release build shows it.

+# Flutter's Gradle plugin enables R8 for release builds and adds this file
+# when it exists; build.gradle.kts needs no change for it to apply.
