-## Dart 2.0 notes
-Version 2.0.5 ships with it's own custom build of `flatc` because this is an extraordinary release to catch-up
-with FlatBuffers for other platforms. This generator can only generate dart code (to avoid generating code for other platforms which isn't released yet).
-On the other hand, the generated code still produces standard binary FlatBuffers compatible with other languages.
-In other words: only `flatc --dart ...` works with this generator, but your app will be able to produce and read standard binary (`Uint8List`) FlatBuffers that are fully compotible with other languages supporting FlatBuffers (e.g. Java, C++, ...).
-
-In the future a common `flatc` binary for all platforms would be shipped through GitHub release page instead.
