If and Else in Flutter

 Flutter if & else: 3 ways of implementation

if and else statements allow developers to execute different blocks of code based on specific conditions. This can help to create more dynamic and responsive user interfaces by allowing the app to respond differently to different inputs or user interactions. 

 

The Problem:

In contrast, Flutter provides an error message when you attempt to use the if-else statement directly within your widget.

            

 Unfortunately, you can’t write if statement inside your widget as if you were writing in your method or function. But there are a few ways you can write a conditional statement inside your widget. Let’s see them.

            A description of how to use an If Else Statement in a Flutter         widget:

1. Using the Ternary Operator
2. Using the Spread Operator
3. Using the Method

• Ternary Operator

       In Flutter, the ternary operator is the same as in other programming languages. It is a shorthand way of writing an if-else statement, allowing for a more concise and readable code.

•  Spread Operator:

        In Flutter, the spread operator (three dots ...) is used to unpack the values of an iterable (such as a list or a set) into another iterable or into function arguments. It allows you to quickly and easily combine multiple iterables or pass multiple arguments to a function.

• Method

   In Flutter, methods are used to encapsulate a set of instructions that perform a specific task or check a specific condition. By using methods to encapsulate if-else statements, you can make your code more organized, easier to read and understand, and more reusable.

Conclusion:

    In this tutorial, we have gone the ways through which we can use if-else block in our flutter application. I hope this will help you out.
