use_truncating_division

Use truncating division.

Description

#

The analyzer produces this diagnostic when the result of dividing two numbers is converted to an integer using toInt.

Dart has a built-in integer division operator that is both more efficient and more concise.

Example

#

The following code produces this diagnostic because the result of dividing x and y is converted to an integer using toInt:

dart
int divide(int x, int y) => (x / y).toInt();

Common fixes

#

Use the integer division operator (~/):

dart
int divide(int x, int y) => x ~/ y;
