.toDouble()

In Dart, the .toDouble() method is used to convert numeric data types, such as int, to their corresponding double-precision floating-point representation.

Syntax

numericValue.toDouble();

• numericValue: Represents the variable to be converted to double.

Example

The following example demonstrates how to use the .toDouble() method to convert an integer to a double:

void main() {
  int number = 3;
  double value = number.toDouble();
  print("Output = ${value}");
}

The above code produces the following output:

Output = 3.0

Note: The output 3.0 is a double. This can be confirmed by checking value.runtimeType.
