Issue with Flutter WEB application. Unsupported operation: Platform._operatingSystem

7sergiy commented 3 years ago

Have faced the following issue while implementing WEB Flutter app:

======== Exception caught by widgets library =======================================================
The following UnsupportedError was thrown building StreamBuilder<ScheduleViewModel>(dirty, dependencies: [MediaQuery], state: _StreamBuilderBaseState<ScheduleViewModel, AsyncSnapshot<ScheduleViewModel>>#c97d2):
Unsupported operation: Platform._operatingSystem

The relevant error-causing widget was: 
  StoreConnector<AppState, ScheduleViewModel>
When the exception was thrown, this was the stack: 
dart-sdk/lib/_internal/js_dev_runtime/private/ddc_runtime/errors.dart 216:49     throw_
dart-sdk/lib/_internal/js_dev_runtime/patch/io_patch.dart 244:5                  _operatingSystem
