StateBuilder<T extends UnitedState<TValue>, TValue extends Object> class

A Widget that allows you to define specific builders for specific states.

This Widget will check the state for you and call the specific builder. The order in which the builders are called are as follows:

if hasError -> errorBuilder else if isLoading -> loadingBuilder else -> successBuilder

Only the successBuilder is required. If your State does not use the isLoading or error properties, you can ommit the optional builders.

If you do pass an error, but have not declared an errorBuilder, this widget will throw an assertion error.
