Some performance tests run "flutter create" to generate platform-specific project configuration files for the test app. These files may be further patched by the test script to apply settings such as the Impeller backend.
The manifests need to be deleted and recreated on each run so that settings applied by previous runs will not be used by the current run.
Initial tap is missing sometimes; either its never delivered or it is
delivered before gesture controller is hooked up.
1: Update MemoryTest to have option `requiresTapToStart` guarding the
new paths
2: Update the two perf tests that appear to be flaky to output when
TAPPED is received
3: Update the MemoryTest to keep tapping while waiting for TAPPED
Tested on devicelab:
* setting iterations=1
* removing the timeout before READY
* running tests in a while loop
Before this change, you could get the test to hang often. After this
change you'll see "tapping device... [x]" where x is the counter.
Fixes https://github.com/flutter/flutter/issues/150096

Reason for reverting: other memperf tests don't wait for or send a TAPPED; so they fail.

This benchmark illustrates the impact that const'ness has on widget build times by building a widget tree with all const-widgets and then building the same widget tree without any const'ness. Local testing with this benchmark running on a Moto G4 shows that const'ness is 13-16% faster.
I'd like to check this benchmark in because the question of how important widget const'ness is comes up every so often. With this benchmark we have up-to-date data to point people to.

Add the missing `Directionality` widget and `await test.pump()` call: commit: 0fd7712fa7
Without the `pump` 1s, it sometimes schedules multiple `handleBeginFrame`s and `handleDrawFrame`s.
For https://github.com/flutter/flutter/pull/144577. There's no promise that the performance will be great when `IntrinsicHeight/IntrinsicWidth` is used extensively but it's not that uncommon of a widget.

This pull request fixes#143803 by taking advantage of Dart's null-aware operators.
And unlike `switch` expressions ([9 PRs](https://github.com/flutter/flutter/pull/143634) and counting), the Flutter codebase is already fantastic when it comes to null-aware coding. After refactoring the entire repo, all the changes involving `?.` and `??` can fit into a single pull request.

This is an attempt at a reland of https://github.com/flutter/flutter/pull/141396
The main changes here that are different than the original PR is fixes to wire up the `flutter test` command properly with the web renderer.
Dual Web Compile has had some issues where `flutter test` is not respecting the `--web-renderer` flag for some reason. I haven't gotten entirely to the bottom of the issue, but for now we need to rever these changes while I investigate. This reverts the following PRs:
https://github.com/flutter/flutter/pull/143128https://github.com/flutter/flutter/pull/141396
While doing this revert, I had a few merge conflicts with https://github.com/flutter/flutter/pull/142760, and I tried to resolve the merge conflicts within the spirit of that PR's change, but @chingjun I might need your input on whether the imports I have modified are okay with regards to the change you were making.
This implements dual compile via the newly available flutter.js bootstrapping APIs for intelligent build fallback.
* Users can now use the `FlutterLoader.load` API from flutter.js
* Flutter tool injects build info into the `index.html` of the user so that the bootstrapper knows which build variants are available to bootstrap
* The semantics of the `--wasm` flag for `flutter build web` have changed:
- Instead of producing a separate `build/web_wasm` directory, the output goes to the `build/web` directory like a normal web build
- Produces a dual build that contains two build variants: dart2wasm+skwasm and dart2js+CanvasKit. The dart2wasm+skwasm will only work on Chrome in a cross-origin isolated context, all other environments will fall back to dart2js+CanvasKit.
- `--wasm` and `--web-renderer` are now mutually exclusive. Since there are multiple build variants with `--wasm`, the web renderer cannot be expressed via a single command-line flag. For now, we are hard coding what build variants are produced with the `--wasm` flag, but I plan on making this more customizable in the future.
* Build targets now can optionally provide a "build key" which can uniquely identify any specific parameterization of that build target. This way, the build target can invalidate itself by changing its build key. This works a bit better than just stuffing everything into the environment defines because (a) it doesn't invalidate the entire build, just the targets which are affected and (b) settings for multiple build variants don't translate well to the flat map of environment defines.
