Avoid annotating with dynamic when not required DRT-W1045
Anti-pattern
Major
AVOID annotating with dynamic when not required.
As dynamic is the assumed return value of a function or method, it is usually
not necessary to annotate it.
BAD:
dynamic lookUpOrDefault(String name, Map map, dynamic defaultValue) {
var value = map[name];
if (value != null) return value;
return defaultValue;
}
GOOD:
lookUpOrDefault(String name, Map map, defaultValue) {
var value = map[name];
if (value != null) return value;
return defaultValue;
}
