Trouble Shooting

The generated inflater code has errors

The most common cause of errors in generated inflater code is due to constructor argument defaults referencing undefined variables. If the referenced variable type is not a primitive, then XWidget can't infer how to generate the default value and will fallback to using the variable reference.

The solution is to manually set the default value for the constructor argument in XWidget's configuration file under the constructor_arg_defaults: key.

xwidget_config.yaml

inflaters:  
  constructor_arg_defaults:
    # example defaults
    "WidgetSpan:alignment": "PlaceholderAlignment.middle",
    "*:colorBlendMode": "BlendMode.srcIn"

See Inflaters Configuration for details.

Hot Reload/Restart clears dependency values

Hot reload loads code changes into the VM and re-builds the widget tree, preserving the app state; it does not rerun main() or initState().

Make sure that you're not binding dependencies in main(), initState() or any other initialization function such as Controller.initialize(). Dependencies should be bound in the build function of your widget. If you are using a Controller, simply override the bindDependencies() method with your implementation and XWidget will handle the rest.
