* Use source list from the compiler to track invalidated files.

* Revert accidental change

* Fix first-time-seen-the-file logic

* Fix/simplify invalidate logic now that we can rely on compiler to let us know what is the cut-off point for invalidation.

* Update devfs mock to accommodate for new fields

* Fix deleted files case

* Analyzer found missing final

* some space formattings

* always use blocks in if-else if a block is used

* format spaces in for and while

* allow multiline if conditions

* fix missing space

* add trailing commas on list/map/parameters

* add trailing commas on Invocation with nb of arg>1

* add commas for widget containing widgets

* add trailing commas if instantiation contains trailing comma

* revert bad change

* Don't send accept/reject if compilation never started.

Ensure that we wait for reject's response since that is async operation.

Fixes https://github.com/flutter/flutter/issues/27120.

* Fix analysis errors

* Rename flag. Ensure we raise it on first compilation too.

These are essentially self-inflicted race conditions. Instead of timeouts we're going to try a more verbose logging mechanism that points out when things are taking a long time.

* Register hot restart service in flutter_tools.

* Report hot reload statistic

* Lints

* Introduce custom dimensions identifiers to track hot reload stats

* Collect devfs stats for better analytics

* Fix fields initialization

* Fix lints

This reverts commit 76f70810.

* Remove many timeouts.

These are essentially self-inflicted race conditions. Instead of timeouts we're going to try a more verbose logging mechanism that points out when things are taking a long time.

* Get the attach tests to pass.

* Apply review comments from Todd

* More review comment fixes

* Put back the extended timeouts here now that I know why we have them...

* update lint list

* enable sort_pub_dependencies

* enable avoid_returning_null_for_void

* enable flutter_style_todos

Fixes https://github.com/flutter/flutter/issues/19273

* Revert "Revert "Run reload asynchronously so that multiple devices can reload in parallel. (#22693)" (#23598)"

This reverts commit 0b68068d.

* Fix refreshViews so it sends app-wide(rather than per-isolate) service request.

Sending per-isolate request caused dead-lock in the engine in case of more-than-one ui isolate.

* Revert "[H] Created a variant of InheritedWidget specifically for Listenables (#23393)"

This reverts commit 93132859.

* Revert "Fix a race condition in vmservice_test.dart (#23529)"

This reverts commit 5e7b0a36.

Revert "Run reload asynchronously so that multiple devices can reload in parallel. (#22693)" (#23598)

This reverts commit 709f54f4 as it seems to have broken two tests: flutter_gallery__back_button_memory, named_isolates_test.

* Run reload asynchronously so that multiple devices can reload in parallel.

* Revert "Remove duplicate code comment in flutter_gallery (#23422)"

This reverts commit 8039620b.

* Revert "Add explicit completed status trace to hot reload and restart commands (#23338)"

This reverts commit 245ef023.

`FlutterDevice.views` is limited by a filter. Pipe this filter up as an
option for the commands that instantiate `FlutterDevice`s. This is the
first change necessary for the CLI tooling to target specific isolates
(#22009).

More work needs to be done after this patch.
* Isolate names are dynamically generated and change every restart.
* This just filters views, not background isolates (`VMService.isolates`).
