Create DevTools => IDE communication channel

[jayoung-lee]

A DevTools -> IDE communication channel is needed to find target clients for a contextual survey about widget inspector.

1. Send the treeNodeSelection hit from DevTools to IDE.
2. IDE stores that information locally to lookup from later.
3. When the lookup data meets a certain condition, trigger a survey.

This may be used for other pulse surveys for DevTools.

What IDEs are in question? Will this mechanism be the same for all IDEs?
Why IDE, not DevTools should trigger a survey?

Here is a summary of the next steps discussed at an offline meeting:

1. Add active survey data to the json file on the flutter website that we already use for devtools surveys
2. From the DevTools server, check for the active survey and compute the logic of whether we should show it (whether we've selected an inspector node within the last 15 days or not).
3. If we should, use dart developer's postEvent API to post an event to the IDE and the IDE can show a toast

I will do #1. What would the reasonable start/end date for this survey?

What would the reasonable start/end date for this survey?

Let's hold off on this until we have a better idea of what the implementation timeline will be on the DevTools and IDE side. If I had to guess, I'd say sometime at the end of Q3 (we'll need to look at the flutter release schedule to ensure we can land the DevTools changes into an upcoming stable release and then set the survey dates based on that). I would expect this type of survey to have a longer running window since we will need to wait at least 15 days before we even can decide to show it to users. Would it be reasonable to run this survey over the course of an entire quarter?

Sure, makes sense. Thanks for keep working on this! :)

the custom stream work @CoderDake did to support a tools stream accomplishes what this issue originally tracked. closing.
