$ dart --version
Dart SDK version: 3.3.0-273.0.dev (dev) (Fri Dec 29 04:03:30 2023 -0800) on "windows_x64"
02/21-05:56:11 ~/issues/g4-3977/antlr/antlr4/Generated-Dart

I have a problem compiling the code. Also, the desc.xml should have "Dart" listed. All the driver code is in the repo, here: https://github.com/antlr/grammars-v4/tree/master/_scripts/templates/Dart

[CorvusYe]

Although the SDK version of the environment is 3.3.0-273.0. dev, this line should play a crucial role. The sdk version can be 2.12 in driver code. We can try changing this version to 2.17 or higher.

I changed the pubspec.yaml as you suggested, but the parser is not producing the correct output. I am expecting errors for examples/LexerElementLabel.g4. The Antlr4 tool, and the CSharp and Java target parsers all report the error, but the Dart target does not. Please update your code and test.

Ok, I will revise it as soon as possible. Thanks for your feedback～
