debugForceFallbacks property

  1. @visibleForTesting
bool debugForceFallbacks
getter/setter pair

When true, shouldUseNativeControls and shouldUseNativeGlass are false, so every widget takes its Flutter fallback on any host.

flutter test runs on the host machine. On a Mac, Platform.isMacOS is true, so a widget test that targets iOS still gets the native views (macOS draws its standard controls natively on every version), while the same test on Linux CI gets the fallbacks. Set this in a test that checks a fallback, and reset it afterwards:

PlatformVersion.debugForceFallbacks = true;
addTearDown(PlatformVersion.reset);

Implementation

@visibleForTesting
static bool debugForceFallbacks = false;
