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.
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
Introduce an overall material "color scheme" and to make it possible to redefine how a component's visual properties bind to the color scheme and to the existing material Theme.
Improve Swift usage in platform_channel_swift some more
Make a bunch of changes that willlarche requested in
https://github.com/flutter/flutter/pull/21712:
* Use `static let` within `enum` namespaces for String constants.
* Use `guard` for early exits and to avoid forced unwrapping.
* Explicitly qualify a selector.
* Fix a retain cycle by using a weak reference.
Make platform_channels_swift use more idiomatic Swift
* Remove semicolons.
* `if (condition)` => `if condition`.
* `Class.init(...)` => `Class(...)`.
* Remove `break` statements from `switch` cases.
* Remove some unnecessary uses of `self`.
* Make CupertinoApp and MaterialApp both use WidgetsApp for Navigator
* Make CupertinoApp and MaterialApp const constructors
* Make WidgetsApp routes aware
* Update tests
* Improve documentation and clean up code.
* Remove "Note that".
The phrase "note that" is basically meaningless as a prefix to an
otherwise fine sentence.
The average frame time of page transitions on Moto G4 is now very
close to 16ms (the last 10 measurements on our dashboard are
between 15.5ms to 16.7ms and half of them are below 16ms).
It is now much faster than when we disabled it (which was at about
35ms). So I think that we should be able to enable it by default.
I'll leave the flag there until we implement the retained rendering
to bring the frame time comfortably below 16ms.
