avoid_inverted_boolean_expressions

Details

DO avoid using inverted boolean expressions unnecessarily.

Unnecessary inverted boolean expression should be avoided since it decreases code readability.

if (!(number > 0)) {}
final text = !(number == 0) ? 'Not zero' : 'Zero';

if (number <= 0) {}
final text = number != 0 ? 'Not zero' : 'Zero';
