feat: implement MacosTable

[pithuene]

I implemented a MacosTable widget which looks similar to the macOS NSTableView (adresses #262 and #199).
The table features ordering by column and row selection.
I have also added some tests for the basic operations.
I am sure there is still a lot to improve, both in code and in UI, but I hope this can serve as a starting point.

This is a screenshot of the table widget running in a process monitor application I am building.
Note that this is running on linux and the font is not the one used on macOS.

Pre-launch Checklist

• I have run dartfmt on all changed files
• I have incremented the package version as appropriate and updated CHANGELOG.md with my changes
• I have added/updated relevant documentation
• I have run "optimize/organize imports" on all changed files
• I have addressed all analyzer warnings as best I could

This is awesome! @GroovinChip, is there something in the way for merging?

Hello @pithuene, and thank you for this PR! I'm excited to see a new widget being added, especially this one!

Please review the feedback I've left and implement the requested changes. Additionally, please update the CHANGELOG.md file.

Thanks!

Hey @GroovinChip, thanks a lot for giving me feedback on my pull request!
I tried to implement your requested changes but am not sure what you were asking for in the changelog file.

Thanks again for your time!

I mean add an entry that describes what the new version adds or changes. If you look at the file you'll understand.

One more thing - can you please post a screenshot of the table in dark mode? I want to make sure that it looks good with dark theme.

Also can you please run flutter format on macos_table_datasource.dart

@pithuene looking forward for the merge! Can you maybe give me an example, how the ordering actually work?

It seems, when I change the datasource like so:

StreamBuilder(
          stream: widget.bloc.items,
          initialData: widget.bloc.items.value,
          builder: (BuildContext context, snapshot) {

....

    changeOrder: (order) {
      // this will update the StreamBuilder
      widget.bloc.changeOrder(order.direction.name);
      return true;
    },

The ordering gets messed up somehow. Can you help me here out. Thanks

[pithuene]

I can take a look @Yetispapa but I would need more context, its hard to tell much just from the code you've shown.
You need to implement the ordering yourself (which you probably did in bloc.changeOrder, but I can't see).
Also I am not sure why you wrapped the table in a StreamBuilder, you should call dataChanged on the data source after the data has changed and let the table do the rebuilding internally.

@pithuene, thanks for the quick repsonse. Alright. Let me check it again.

[GroovinChip]

@pithuene anything new to report on this?

[pithuene]

@GroovinChip not yet. I've been too busy the last few weeks, might find the time next week though.

No problem my dude, take your time. Your life comes first :)
