Chapter 3 | Type Casting in Dart

In this chapter, we will learn how to convert the data type of one variable into another.

• String to int Conversion: we use int.parse() to convert a string into integer if it’s compatible.
• String to double Conversion: we use double.parse() to convert a string into floating point value (like 2.2) if it’s compatible.
• int to String Conversion: we use toString() to convert an integer value into a string value.
• double to String Conversion: we use toStringAsFixed() to convert a double value into a string value.

Here’s the source code (wait for it to load):

That’s it for this chapter. See you in the next one. Bbye!
