Is your feature request related to a problem? No

A clear and concise description of what the problem is.
What about a shortcut that prints the hover application screen? Android emulator has this feature and I think it's very useful.

Describe the feature you'd like

Something like Alt + PrtScr

Would you like it to only be available in debug or always?

[ericdallo]

@jld3103 I didn't know that there's a hover debug mode, or you are referring to flutter's debug mode?

[jld3103]

Yes

[ericdallo]

I don't see any problem the print shortcut works for non debug profile too, but if you want to restrict only for debug, I'm okay with that :)

It's already available in the flutter toolchain!

flutter screenshot --observatory-uri=http://127.0.0.1:50300/XXXXX --type=rasterizer

$ flutter screenshot --helpTake a screenshot from a connected device.

Usage: flutter screenshot [arguments]
-h, --help                      Print this usage information.
-o, --out=<path/to/file>        Location to write the screenshot.
    --observatory-uri=<URI>     The observatory URI to connect to.
                                This is required when --type is
                                "skia" or "rasterizer".
                                To find the observatory URI, use
                                "flutter run" and look for "An
                                Observatory ... is available at"

                                currently being displayed
                                (including content not rendered by
                                Flutter, like the device status
                                bar).

Thank you very much @pchampio, It works!
If there was any way of getting this XXXXX easily, I could make some shortcut for hover.el to take the screenshot :thinking: :pensive:

[pchampio]

Haha, I'm working on this at the moment^^

[ericdallo]

Thanks! :crossed_fingers:

[pchampio]

I have removed the auth-code from the observatory URL. engine/switches.h This wasn't an option before. No more XXXXX at the end of the url.

I've also enable enable-service-port-fallback engine/switches.h, this way, multiple hover run can be launched without having to use the hover run --observatory-port flag.

In the context of hover.el, It's up to you to provide an --observatory-port that isn't already used, relying only on the default port will cause issues when multiple user are running hover run.

[pchampio]

fixed in the latest version of hover.
go get -u github.com/go-flutter-desktop/hover

[ericdallo]

Uow, nice!
I'll sure implement this :D
Thanks for your help @pchampio

[pchampio]

@ericdallo could you read https://github.com/go-flutter-desktop/go-flutter/issues/129#issuecomment-601852948
I'll like your opinion, and how are you performing hot reload? (manually or on save, if on save, are you sending 'r' key-presses into the hover proc)

[ericdallo]

@pchampio, hover.el has the option to manually input commands like r or R, but also allows keybindings to do that, like in this example. It has the feature that on file save, it triggers auto-reload(sending the r command to hover background process).
