* add missing trailing commas

* add more missing trailing commas

* add more and more missing trailing commas

Currently Linux builds override the default BUILD mode by putting it in
the generated config. That makes it sticky for manual runs of make,
which is inconsistent with how other platforms work.

Instead, pass the build mode as a command-line override, the same way
someone would if building directly with make. This makes the flow of
controlling the mode less confusing.

Fixes #41528

* set the copyWith toggleButtonsTheme argument type to ToggleButtonsThemeData

* add a ThemeData.copyWith test

* [flutter_tool] Report to analytics when the tool is killed by a signal

* Fix analyzer lint

* Fix visbility of web server device when Chrome is not available

* Add tests

* Update workflow test

* Fix tests to not rely on Chrome being on the underlying machine

* Retry devfs uploads in case they fail.

Fixes #34959.

TBR: @goderbauer

This reverts commit baea9bf7.

Additionally,   we let the test run on mac8 with iphonexs because the test won't run on Xcode 10.1 (mac3-7). Hence we force it to run on mac8 which currently has Xcode 10.2.

This reverts commit 67b5bdf9.

Reason: it broke device lab.

TBR: @goderbauer 

This reverts commit f1e7fe81.

This fix is in https://github.com/flutter/packages/pull/39

This re-lands #41417 with a slight change that will hopefully not tickle the analyzer as it did before. The last time I tried to land this, the analyzer succeeded for the analyze step in Cirrus, and locally, but failed in an integration test.

* remove splash logic

* update tests

This adds a description of the command needed to run the driver test
