Flutter plugins follow Google style—or Flutter style for Dart—for the languages they use, and use auto-formatters:

Dart formatted with dart format
C++ formatted with clang-format
- Note: The Linux plugins generally follow idiomatic GObject-based C style. See the engine style notes for more details, and exceptions.
Java formatted with google-java-format
Objective-C formatted with clang-format
