[flutter_tools] _Exception: Exception: analysis server exited with code -2 about flutter HOT 6 OPEN

From the tool, the exception is being thrown from https://github.com/flutter/flutter/blob/beta/packages/flutter_tools/lib/src/commands/analyze_once.dart#L100

Earlier, we spawn the analysis server here: https://github.com/flutter/flutter/blob/beta/packages/flutter_tools/lib/src/dart/analysis.dart#L57

    final String snapshot = _fileSystem.path.join(
      sdkPath,
      'bin',
      'snapshots',
      'analysis_server.dart.snapshot',
    );
    final List<String> command = <String>[
      _fileSystem.path.join(sdkPath, 'bin', 'dart'),
      '--disable-dart-dev',
      snapshot,
      '--disable-server-feature-completion',
      '--disable-server-feature-search',
      '--sdk',
      sdkPath,
      if (suppressAnalytics) '--suppress-analytics',
      if (_protocolTrafficLog != null)
        '--protocol-traffic-log=$_protocolTrafficLog',
    ];

Did this just start with beta/3.19.0-0.4.pre?

It's not much help, but the only explicit invocations of exit that I can find that could have a value of -2 are during the "training" used while building the snapshot in order to improve performance. They shouldn't occur while using the snapshot.

I wonder if -2 means killed by an operating system signal?

It might. As far as I can tell there's no standard for what even a subset of exit codes mean, other than 0 appears to always mean "success" (though I did find one resource that claimed that non-zero doesn't always mean failure).

In any case, an integer encoding is a pretty poor way for any system to communicate with humans. 😦

You don't need to convince me, but such is my life...
