What is int flutter?

int class Null safety. An integer number . The default implementation of int is 64-bit two’s complement integers with operations that wrap to that range on overflow. Note: When compiling to JavaScript, integers are restricted to values that can be represented exactly by double-precision floating point values.

Declaring Variables In Dart Variables are declared using the var keyword followed by variable name that you want to declare . Dart is a type inferred language, which allows compiler automatically infer(know) the type of data we want to store based on the initial value we assign.
