Use truncating division.

This rule is currently experimental and not yet available in a stable SDK.

This rule has a quick fix available.

Details

#

DO use truncating division, '~/', instead of regular division ('/') followed by 'toInt()'.

Dart features a "truncating division" operator which is the same operation as division followed by truncation, but which is more concise and expressive, and may be more performant on some platforms, for certain inputs.

BAD:

dart
var x = (2 / 3).toInt();

GOOD:

dart
var x = 2 ~/ 3;

Usage

#
