  • This component allows users to increment or decrement a value by clicking + and - signs on stepper.

  • We can use a stepper to:
      1. Change a value up or down by 1
      1. Operate strictly over a prescribed range.
      1. Step by specific amounts over a stepper’s range of possible values
 

1. Create Stepper

 

what is Strideable?

A type representing continuous, one-dimensional values that can be offset and measured.

You can use a type that conforms to the Strideable protocol with the stride(from:to:by:) and stride(from:through:by:)functions. For example, you can use stride(from:to:by:) to iterate over an interval of floating-point values:

 

  1. Create an integer variable with value 10, and bind it into value: with $ sign
 
  1. add a variable inside the text, using \(variable)
 
 

2. Create new stepper

We will create a rectangle that changes the size by clicking the stepper

 
 
  • Choose a stepper with onIncrement and onDecrement
 
  • Create integer 0 variable
 
  • Add add into a rounded rectangle width
 
  • add variable into the increment and decrement
 
  • Add easeInOut animation to Stepper by creating outside function
 
 

Stepper enables users to increase or decrease a value by clicking the + and - signs.

The view element can be edited or modified smoothly using withAnimation.

I'm uncertain about the product number as Fynn hasn't requested a spec sheet for that product yet.
