In this tutorial, we will learn how to use the Provider
widget to pass data to child widgets. The Provider
supplies specific data to its child widgets, and these child widgets can access the data using the Provider.of
method.
In the example above, the Provider
holds a key called provider-key
and a value called value from provider
, and uses CustomWidget
as its child widget. Inside the CustomWidget
, it calls Provider.of
to retrieve the value associated with provider-key
and displays it on the screen.
This approach allows child widgets to easily access the state managed by parent widgets, enabling efficient data management and enhancing component reusability.
The Provider
widget can be very useful in various scenarios, especially when data needs to be shared across multiple levels of an application.
