+DART *dart.vim* *ft-dart-syntax*
+
+Dart is an object-oriented, typed, class defined, garbage collected language
+used for developing mobile, desktop, web, and back-end applications. Dart uses
+a C-like syntax derived from C, Java, and JavaScript, with features adopted
+from Smalltalk, Python, Ruby, and others.
+
+More information about the language and its development environment at the
+official Dart language website at https://dart.dev
+
+dart.vim syntax detects and highlights Dart statements, reserved words,
+type declarations, storage classes, conditionals, loops, interpolated values,
+and comments. There is no support idioms from Flutter or any other Dart
+framework.
