MultiStateHolder class

MultiStateHolder

A StateHolder that merges multiple StateHolders into a single linear widget tree. It is used to improve readability and reduce boilerplate code of having to nest multiple layers of StateHolders.

As such, we're going from:

import 'package:state_holder/state_holder.dart';
....
....
StateHolder<Something>(
  builder : (context) => Something(),
  child : StateHolder<SomethingElse>(
    builder : (context) => SomethingElse(),
    child StateHolder<AnotherThing>(
      builder : (context) => AnotherThing(),
      child : App(),
    ),
  ),
),
....
....

To:

import 'package:state_holder/state_holder.dart';
....
....
MultiStateHolder(
  stateHolders : [
    StateHolder<Something>(
      builder : (context) => Something()
    ),
    StateHolder<SomethingElse>(
      builder : (context) => SomethingElse(),
    ),
    StateHolder<AnotherThing>(
      builder : (context) => AnotherThing(),
    ),
  ],
  child : App(),
),
