Form with multiple steps (wizard style) in Flutter - Best approach

Question

I need to prepare a screen to create a new record for a table with several fields. Some fields are conditional on previous fields. My initial attempt includes a TabController/TabBarView/Tabs set where every tab is a part of the form.

My two problems there are:

• I cannot seem to be able to hide the "tab" (icon/text) itself in a TabBarView ( I want to use a button for "Next Step")

• Even if I live with that, if I build a widget for each tab, I'd need a GlobalKey for every Form (one for each tab) as they cannot be shared.

Is there another way to do this, with another widget or approach so as to have a Form divided in several steps/screens and then submit the whole data as a whole?

Answer 1

You can use the Stepper Widget. it can enable you from making vertical or horizontal wizard from multiple steps.

Stepper({
  Key key,
  @required this.steps,
  this.physics,
  this.type = StepperType.vertical,
  this.currentStep = 0,
  this.onStepTapped,
  this.onStepContinue,
  this.onStepCancel,
  this.controlsBuilder,
})
