Hi, whats is BuildContext and how I know that I have to pass this? When do I need a context?
Hi @gisesonia, thanks for the question! The BuildContext is a handle to where you are in the widget tree. You pass it to widget builder methods, such as overrides of the build() method. When getting started with Flutter, that’s the main place where you’ll see it.
You also will use it when calling of methods, like when showing a Snackbar using something like Scaffold.of(context).showSnackBar(...). You can access the context within build methods, and also get it from the State.context member property.
Thank you. I will look for more examples.
