*Flutter Web and Streams | Form validation in Flutter streams *
We will cover briefly about
1. Streams inside Forms
2. Using Flutter Hooks
Streams inside Forms
The parent widget is a HookWidget.
Inside this widget, we have created a form having 3 fields
The first field accepts anything except a blank
The second field accepts any valid integer
The third field accepts any valid double
Using Flutter Hooks
We use the useStreamController from the Flutter Hooks for our stream.
Notes:
Creates an [StreamController] automatically disposed of.
By default, the stream is a broadcast stream
