Hello everyone!

Today I am here to show you how you can get a real time input from the user in the dart programming language. It is common that we have to deal with the dynamic values and each user can give a different value. So we can read them easily and implement them in the code to get the desired results according to the entered value.

How to get user input in dart programming language?

In order to take a user input we have to use a specific library in dart language. We have to import import 'dart:io'; because it deals with the input and output values.

Here you can see the simple syntax of getting input from the user and sowing the outputs to the user.

• Simply we use stdout.write() to print any statement and show it to the user.

• In order to get an input from the user we use stdin.readLine(). We get the input from this method and store that input in a variable to use it later.

• You can see I got the input from the user and stored it in the variable name and then used it back to show it to the user.

How to check the number is an even or odd?

In order to further explain the concept of getting user input and using it in the program and then showing the results on the basis of the user input I have tried to write a program which will identify whether the entered number is even or an odd.

• You can check first of all I have written the line of code to ask the user to enter a number.

• Then I am getting the user input.

• After this I have implemented a condition to check the number whether it is even or odd.

You can see the program is working very well and it is analyzing the user input and then showing the respective results.
