flutter "toggle debug paint" command

[shamrin]

Default flutter app template has the following comment:

// Invoke "debug paint" (press "p" in the console where you
// ran "flutter run", or select "Toggle Debug Paint" from the
// Flutter tool window in IntelliJ) to see the wireframe for
// each widget.

It would be nice if Dart-Code would support "debug paint" as well. There are more commands that flutter run supports, but this was the most helpful in my opinion. And "full restart": #368.

@devoncarew @eseidelGoogle Is this command available via flutter run --machine? I can't see it listed on the daemon page though there is talk of calling service extensions - is it one of them? If so, where can I find the info? (I had a quick search through atom-flutter source but can't see anything that looks like this).

[devoncarew]

@DanTup, the atom-flutter sources have not been maintained - I would not look to them for examples. The IntelliJ sources (Flutter related) are here: https://github.com/flutter/flutter-intellij.

For this, we're calling a service extension - contributed by the flutter runtime - called ext.flutter.debugPaint (https://github.com/flutter/flutter-intellij/blob/210cec052c4ed3a5f4fb77e2d58a62bfdc0d800f/src/io/flutter/view/FlutterView.java#L167).

And specifically, we're using the daemon API to proxy the service extension call (app.callServiceExtension, https://github.com/flutter/flutter-intellij/blob/master/src/io/flutter/run/daemon/DaemonApi.java#L84).

Hope that helps -

@devoncarew Perfect, thanks! Are there any docs on these service extensions, or is the IntelliJ source the best place to see everything available?

I've added all of the commands I could find in the intelliJ file, will be included in v2.3 (with the exception of opening Observatory timeline, that may or may not be included in 2.3).

[devoncarew]

No docs as such; the IntelliJ sources will be the best system of record for a bit. You can also skim the flutter repo code, and you should be able to get a list of service protocol extensions from the protocol.
