* move analysis_options to package

Usages of ParagraphConstraints (from dart:ui) whose constructor could be
const as of flutter/engine#7346 are currently marked //
ignore:prefer_const_constructors in the framework until all
Google-internal embedders have been updated to an engine version that
includes the above change. These were initially updated in engine roll
flutter/flutter#26252, but broke internal embedders.

We should re-enable use of the const constructor in those cases once
internal embedders are updated.

See: https://github.com/flutter/flutter/issues/26390

80 characters was short enough that after the XML boilerplate in the
response, all we got was 'The'.

When downloading the ObjC/Java API docs, check the HTTP response status
code and if not 200, attempt up to 5 times before giving up.

Disables the cache by default and deprecates the API for setting its
size.

flutter/flutter#26081

Now that we have our DNS mapping we should refer to the master docs site that way everywhere.

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.
