constant_ identifier_ names
Prefer using lowerCamelCase for constant names.
Details
#PREFER using lowerCamelCase for constant names.
In new code, use lowerCamelCase
for constant variables, including enum values.
In existing code that uses
ALL_CAPS_WITH_UNDERSCORES
for constants, you may
continue to use all caps to stay consistent.
BAD:
const PI = 3.14;
const kDefaultTimeout = 1000;
final URL_SCHEME = RegExp('^([a-z]+):');
class Dice {
static final NUMBER_GENERATOR = Random();
}
GOOD:
const pi = 3.14;
const defaultTimeout = 1000;
final urlScheme = RegExp('^([a-z]+):');
class Dice {
static final numberGenerator = Random();
}
