title: How to dynamically change the number of steps in stepper in flutter?
body: <p>I am making a validation form in a stepper format in <em>flutter</em>. Each step has a validation form.</p>
  
  <p>When first opening the page, there is only one step.  I want the user to click continue and get one more stepper (i.e Step 2 and get one more step by clicking continue in step 2.)</p>
  
  <p>I have tried to change the number of steps by adding one more step to the list and updating when <code>changeCurrentStepContinue</code> is called, but it can't increase the number of steps showing error. On going back and again going forward, I get the updated list.</p>
  
  <p>So how can I change the number of steps on the same page by clicking continue in each step?</p>
