Before this change, rolling back a patch relied on deleting the patch
file from the server completely. This PR implements a more reliable
approach where developer needs to create a physical rollback patch file.
This is more robust to mistakenly taking down a patch from user devices.

When setting the Fuchsia logging function, it should happen before any
initialization code, as init can still cause warning/error/info messages
to get printed to logs. Since the default stderr/stdout fd's aren't
correct, this can cause a program to crash for unclear reasons.

* update docs for editable_text (TextField)

* typo, clarify behavior when lines > 1

* Check for bad configuration in Xcode10

Fix project directory has spaces lead to compile error when use 'flutter create -t module'command (#23817)

The variable isn't interpolating because it's using "${}" when ruby uses "#{}".

* the onStart callback will report the location of the pointer where it wins the gesture arena by default instead of the pointer down location. Fixes all tests related to changing this default value.

* Remove *.lock from gitignore

* Remove pubspec.lock from gitignore

* Add source line to snippet metadata

* Force DatePicker value to stay within firstDate and lastDate upon year change

* updated per review feedback

* Revert "Replace netls and netaddr with dev_finder (#26090)"

This reverts commit eee154af.

Looks like the bot is working as we want, so I don't need to be cc'ed on all of the closures any more.

* Add Robert Penner’s easing functions

These easing functions are the most popular functions in use on the web
and other platforms. Including them in Flutter will encourage users to
create more engaging and attractive animations.

Adds avatarBorder property to SelectableChipAttributes and uses the outer path to draw the darkened layer.

This reverts commit 08538f91.

* Adds start behavior option to the drag gesture recognizer and makes it the default option when a drag gesture recognizer is created. Also fixes all the tests to work correctly with the new default behavior.
