ProvideMulti class

Widget that rebuilds on change using multiple values provided by a ProviderNode.

ProvideMulti is the functional equivalent of chained Provide widgets. It will call builder whenever any of the requested values changes.

As with Provide, the builder should just build as little as possible to optimize performance.
