flutter_driver library Null safety
Provides API to test Flutter applications that run on real devices and emulators.
The application runs in a separate process from the test itself.
This is Flutter's version of Selenium WebDriver (generic web), Protractor (Angular), Espresso (Android) or Earl Gray (iOS).

Mixins
- DeserializeCommandFactory

Constants
- find → const CommonFinders
-
A convenient accessor to frequently used finders.
CommonFinders._() - kBuildBudget → const Duration
-
The maximum amount of time considered safe to spend for a frame's build
phase. Anything past that is in the danger of missing the frame as 60FPS.
Duration(milliseconds: 16) - kBuildFrameEventName → const String
-
The name of the framework frame build events we need to filter or extract.
'Frame' - kRasterizeFrameEventName → const String
-
The name of the engine frame rasterization events we need to filter or extract.
'GPURasterizer::Draw' - kUnusuallyLongTimeout → const Duration
-
How long to wait before showing a message saying that
things seem to be taking a long time.
internal">@internal
Duration(seconds: 5)
