Using the same GitHub Action which is already in use for the unit tests, add a nightly build for all flutter supported platforms.

The configuration of the jobs is basically that which the readme of the Action is outlining: I do not know which platforms are intended to be supported - this is the maximum possible, feel free to adjust accordingly.

Hello devolo,

I found this repo, while looking for the devolo Cockpit source code.

In the readme, Linux is listed as a supported platform, however it does not work for me.

I understand this is probably a WIP project, but throught I should let you know anyhow. Your open-source approach to the re-write is greatly appreciated.

Looking at the repo, as there is a gitlab CI file, I am guessing somewhere a pipeline is executed.

As to also automatically test GitHub pull requests, one idea would be to add a GitHub Workflow which does the same as the GitLab CI.

This PR is implementing a GitHub Workflow which does roughly the same as the GitLab CI automation.

Hello Devolo team!

Usually the usage of the English word "information" is uncountable.

Me reading this message made me assume it was a translation mistake, the Wiktionary [1] entry lists it as usually uncountable.

With this PR I can only talk for myself, and perhaps if you have a translation team ask them what they say?

btw: many thanks for the recent updates, now I can run the application locally without any problems.

Update "provider" dependency to v6.

This as to address the following build error:

Fix compilation errors in the main and lib/shared/informationDialogs files.

Without these adjustments, the project does not build on my local machine.

Additionally, the automatically updated files following executing flutter pub upgrade are also added.

Microsoft Visual Studio code supports an easy start in development using devcontainer. They come will all the packages that I need to start development right away.

The devcontainer was developed and tested on Linux, other OS still need some love.

This devcontainer requires two things: you need to start the devolonetsvc on the host system to see devices and you need to run 'xhost +local:' if you want to see the UI while debugging.

Hello devolo team,

I just had to compliment the team and the recent development efforts!

The adjusted/new(?) device icons and dark mode looks absolutely great.

Perhaps its worth updating the screenshot in the readme as a way to show the work?

Fix the build on Linux by replacing the git:// prefix with https://.

Without this, the following error is shown:

➜  cockpit_open_frontend git:(develop) ✗ flutter pub upgrade

For further details, see this issue:

Lastly, this PR also suggest to document a workaround for another error, one which have happened to me after each flutter upgrade.

Inspired by #8 I created an action that runs the unit test on push. As far as I can see, it should do the same as the gitlab CI but as efficient as possible.
