Allow debugger debuggerType to be provided explicitly by a launch configuration #5535
Description
Describe the bug
A clear and concise description of what the bug is.
I am developing a VSCode extension that will auto-attach a Dart debug session. The program that I am trying to run will always be a Dart application.
If the workspace contains a root pubspec.yaml file that references Flutter, the debuggerType is forced to DebuggerType.Flutter.
Expected behavior
A clear and concise description of what you expected to happen.
If I supply
const attached = await vscode.debug.startDebugging(workspace, {
name: debugSessionName,
request: "attach",
type: "dart",
vmServiceUri: debugUrl,
debuggerType: 0 // DebuggerType.Dart
});I expect the debuggerType to remain as DebuggerType.Dart
