* Add currency formatting for l10n tool, fix positional vs named params

[flutter_tools][web] Add support for web app manifests and arbitrary resource files (from web/) (#48316)

This reverts commit 1613a62e.

Step 1 of 2: Warn about Flutter's FloatingActionButton dependency on ThemeData accent properties (#48435)

This simplifies the diagnostic output for the Shortcuts widget so that if a debugLabel is supplied, then that is printed instead of the full list of shortcut keys in the map. Also, the output of the shortcut map is simplified to have the list of keys presented in more readable text.

* Implement reverseTransitionDuration in TransitionRoute

Document reasoning for why CustomMultiChildLayout size can't depend on children and how to do it (#48451)

This reverts commit 945f206b.

Moves the checks that projects have been configured for desktop to a lower level, where they will cover more codepaths (e.g., 'run'), and improves them to check for native build projects, rather than just directories, to catch cases where the directory exists (e.g., due to accidental creation of generated files).

Also adds links to the error messages pointing to instructions on adding desktop support to a project.

This adds CatmullRomCurve animation curve, and a CatmullRomSpline, which is what it uses to do interpolation.

This allows us to create animation curves which can smoothly interpolate the values given to the curve.

Since I've introduced a 2D spline curve, I also created a Curve2D base class for such parametric curves.
