[REQ] [Dart] Use Dart SDK to generate Dart keywords for reserved words list
Created by: nickmeinhold
Is your feature request related to a problem? Please describe.
A recent PR improved the Dart generator by updating the reserved words. When I went through and checked if there were any more Dart keywords missing, there were a few still missing and it was quite time consuming to determine exactly which words were missing as it is a hard-coded list.
Describe the solution you'd like
Use the Dart SDK to automatically generate the Dart keywords and have the dart generator use the generated set of words.
Describe alternatives you've considered
We could keep the list of reserved words hard-coded in and just add a comment that the list was generated by the SDK with a date and Dart version so we know when the list needs to be updated.
