  Stepper:</p>
  
  <pre><code>  body: Container(
              child: Stepper(
                physics: BouncingScrollPhysics(),
                steps: stepsStammdaten(),
                currentStep: currentStep,
                onStepContinue: next,
                onStepTapped: (step) =&gt; goTo(step),
                onStepCancel: cancel,
              ),
  
  
  Step(
            state: StepState.indexed,
            isActive: true,
            title: const Text('Rejkla'),
            content: ListView.builder(
                shrinkWrap: true,
                itemCount: this.index,
                itemBuilder: (context, index) =&gt; this._buildRow(index),
              )
            ),´´´
  
  The method buildRow() contains a ListView
  
   return ListView(
          physics: const AlwaysScrollableScrollPhysics(),
          shrinkWrap: true,
          children: &lt;Widget&gt;[
  
  // Here are some text inputs
  
  ]);
  </code></pre>
