prefer_int_literals

Prefer int literals over double literals.

DO use int literals rather than the corresponding double literal.

BAD:

const double myDouble = 8.0;
final anotherDouble = myDouble + 7.0e2;
main() {
  someMethod(6.0);
}

GOOD:

const double myDouble = 8;
final anotherDouble = myDouble + 700;
main() {
  someMethod(6);
}

To enable the prefer_int_literals rule, add prefer_int_literals under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - prefer_int_literals

If you're instead using the YAML map syntax to configure linter rules, add prefer_int_literals: true under linter > rules:

linter:
  rules:
    prefer_int_literals: true
