* add crash reporting without enabling it

* do not drop futures on the floor

* return exitCode from executable run

* debug travis

* remove unnecessary todo

* rename local fs getter

Fixes #8557

* Use exact Ahem and exact dimensions for test

* use ‘px’ everywhere

This feature lets you see a portion of the next and previous page in a
PageView.

Fixes #8408

Previously, we would create a simulation whose initial velocity did not match
the requested parameters. We now compute the parameters for the simulation in a
way that ensures all the math works out.

Fixes #8255

* fix FLUTTER_ANSI_TERMINAL check

should have been included in the previous PR :(

* review comments

Prevent the app bar header from being overscrolled on iOS by setting
paintOrigin to the overlap.

Also make locals final where possible.

Fixes #8478

* Enable Hot Reload on Windows (backed by gen_snapshot)

\o/

Two caveats:
* Hot Reload on Windows is slower than on other platforms because gen_snapshot is slower then sky_snapshot
* We currently cannot hot reload projects with spaces in the path

* enable tests

The gradle build scripts can be configured to output different
application IDs for different build types, so we need to examine the
built .apk to figure out the name of the package and activity.

Re-landing this change, updated to only get information from the .apk
if it exists.

Since the tools create an AndroidApk instance early, even before we've
actually built an .apk, we have to create a new instance after building,
so we can start the right app/activity.

Fixes #8327.

This happens when, for instance, you go back then forward quickly.

* Improved defaults for scroll view primary-ness

* Vertical scroll views default to primary:true.
* Horizontal scroll views default to primary:false.
* If a scroll view is primary and it got a non-null inherited primary
  scroll controller, it introduces a primary scroll controller inherited
  with a value of null for its descendants.

ScrollController now multiplexes writes to all registered positions;
reads of position continue to assert that only one position is
registered. Reads still require a single position.

* Add cupertino to gallery and add CupertinoButto

* Use single quotes

* Add disabled state

* Some review notes

* Make button animation more responsive and tweak timing

* Renamed things Cupertino

* Button with background, move cupertino demos, move material demos

* Move 2 level list too

* Refactor various demo route names

* Some review notes

* More reviews and add test

* Linter as

* Move private constant up

This got missed in the last sweep due to concurrent PRs

This one comes with sweet Unicode support for Windows!

Ensure that read and write operations fail on ScrollControllers
associated with a number of positions other than 1.

Using these physics avoids a problem whereby the scroll view isn't scrollable
due to lack of content and therefore cannot trigger the refresh indicator.

Fixes #8432

This widget is useful on its own. This patch factors it out of AppBar so
folks can use it separately.

Fixes #8489

* [devFS] Use URI to represent paths on device

Previosuly, regular file paths in the format of the host platform were used to represent paths on device. That works when host and device share the same (POSIX) file path format. With a Windows host, this breaks. URIs are the solution as they are platform independent and the VM service on the device already interpreted the file paths as URIs anyways.

* review comments

* switch to file paths

* fix tests on Windows

This TODO was fixed by the transition to `Finder` objects.

This ensures that both timer/microtask queues are cleared out rather
than assuming that all work is completed in a specified amount of time.

New concepts: PlatformMessageChannel (basic message send/receive superseding some existing  PlatformMessages methods), PlatformMethodChannel (method invocation and event streams), pluggable codecs for messages and method calls: unencoded binary, string, json, and 'standard' flutter binary encoding.

Instead, actually exit the tool.

Fixes #8363.

This is apperently breaking some customers.

If this gets submitted, we should investigate why self-package imports
don't work for certain customers.
