Fixes #22789

* Refactor AnimatedSwitcher

This is mostly just a little bit of cleanup with hopefully no semantic
changes, done to teach me how the code works so that I could fix a bug.

* Add debugging information to AnimatedSwitcher

* Fix AnimatedSwitcher to handle the case of back-to-back changes

Previously, if a child was replaced the very next frame after it was
added, we'd get confused because we tried to reverse the controller,
which causes us to remove the child from the going-away list, before
we had added the child to the list in the first place.

The fix is just to move the reverse to after the add.

We'll roll this back as soon as the Dart analyzer gets upgraded in
Google3.

* [Typo] it it -> if it

Obviously a small change, looks like a little copy-paste accident.

Adds a Fuchsia compatibility function that allows for connecting to a
specific Isolate by name when running Flutter Driver on a Fuchsia
device.  This will check over multiple Dart VM's in an attempt to find
an Isolate by its name.

* Adds comments clarifying the procedure used to render the menu as well as tests verifying various dropdown menu button positioning and initial scroll states.

Fixes a gradle error where it was failing to find a plugin because of an absolute path in the .flutter-plugins file instead of a relative path.

I had originally removed this variable because I thought it was redundant with the projectDir, but apparently I was wrong about that (one resolves to a relative path, and one resolves to an absolute path).

This PR reverts that part of the change and reintroduces the (not really) redundant variable.

A few changes:

* Remove the search tip (it relies on searching for the new keyword which we no longer use)
* Remove mentioning of examples that are either stale or only used for internal purposes (such as test)
* Cross-link to the samples repo

Revert "Turn on line wrapping in usage and status messages, adds ANSI color to doctor and analysis messages. (#22656)" (#22759)

This reverts commit e4386321
because it breaks 160 benchmarks, and several devicelab tests,
due to changing the format of the output.

Turn on line wrapping in usage and status messages, adds ANSI color to doctor and analysis messages. (#22656)

This turns on text wrapping for usage messages and status messages. When on a terminal, wraps to the width of the terminal. When writing to a non-terminal, wrap lines at a default column width (currently defined to be 100 chars). If --no-wrap is specified, then no wrapping occurs. If --wrap-column is specified, wraps to that column (if --wrap is on).

Adds ANSI color to the doctor and analysis output on terminals. This is in this PR with the wrapping, since wrapping needs to know how to count visible characters in the presence of ANSI sequences. (This is just one more step towards re-implementing all of Curses for Flutter. :-)) Will not print ANSI sequences when sent to a non-terminal, or of --no-color is specified.

Fixes ANSI color and bold sequences so that they can be combined (bold, colored text), and a small bug in indentation calculation for wrapping.

Since wrapping is now turned on, also removed many redundant '\n's in the code.

This all happened because I was trying to be a little too helpful...

Part of the job of the "create" command is to recreate missing pieces of existing projects, and now that the default has changed, I wanted to make it so that if someone had created a default flutter create project before, that they could run a default flutter create there again, and not have it trashed by using the new default template (application) over the old one (app).

This meant I had to detect what type of project it was. Unfortunately, in the past we didn't write anything in the .metadata file to identify the type of project, and since the goal was regenerating missing files, I can't count on anything existing, so it's just a heuristic match.

This simplifies the heuristics down to just detecting the difference between "app" and "application" projects, and only detect the other types if they're explicitly listed in the .metadata file (I changed the code in my original PR to add the project type to the .metadata file). People used to have to specify the type for those anyhow, so it shouldn't be a surprise to users.

So, the main difference in the new heuristics from my last attempt is that if you have a directory that has some other stuff it (like maybe a "plugin" project), then we'll recreate (pronounced "mess up") the project using the "application" template, but that was true before (except it would use the "app" template).

Fixes #22726

This reverts commit 3c56e6c7.

It breaks the AOT build.
