Track active changes in the application and show list in manage page.

[codinesh]

Fixes #1438, by displaying a section for installing/uninstalling snaps.

To Listen to the changes from Snap details page, tapped on to SnapModel._activeChangeListener to know the installs, uninstalls and change updates. This will call the ManageModel to maintain the list of active snaps.
Scope of this change to track the changes made from this app, as a workaround to an issue in /v2/changes api, which doesn't give enough information to identify corresponding snap from the response.

Workaround is discussed #1438 (comment).

Sounds good, thanks.

Great work @codinesh! Just a few points:

• when there are no apps being installed, this section will be hidden, correct?
• would be nice to display the option to cancel the installation
• maybe we can remove the more options button [ ... ] since it's probably not very useful or no actions to be taken while the installation is in progress

did a quick mock-up of how it could look like:

Thank you

Yes, that is the behavior..

Hello @anasereijo,

maybe we can remove the more options button [ ... ] since it's probably not very useful or no actions to be taken while the installation is in progress

Should we keep the [...] options button to make it consistent with other two sections. Please see the screenshot. Since the item is to open, will be navigated to snap detail page.

Please let me know what you thing, change is simple in any case.

Thank you

Hi @anasereijo please have a look at this comment and share your opinion.

Hi @codinesh, apologies for my late reply.

Good catch! we should keep consistency with the other sections indeed. so lets keep the button [ ... ] whilst the snap is installing.

thank you!

Thanks a lot for you hard work @codinesh! I think it helped a lot in bringing forward the final design of this. <3
I'll close it since it's been superseded by #1810.
