Compiler error on flutter run causes tool to crash

[Hixie]

1. flutter create compiler_crash
2. Replace lib/main.dart with:

import 'package:flutter/material.dart';

void main() => runApp(test: null);

3. In the compiler_crash/ directory, run flutter run.

Output:

$ flutter run
Launching lib/main.dart on Pixel 3 XL in debug mode...
Running Gradle task 'assembleDebug'...                          


Compiler message:

void main() => runApp(test: null);

This isn't a tool crash, but the error message there shouldn't contain a stack trace

[jonahwilliams]

I guess per the definition of crash in tags "stack traces logged to console" it is though XD
