avoid-dynamic
Warning
Warns when dynamic
type is used as variable type in declaration, return type of a function, etc. Using dynamic
is considered unsafe since it can easily result in runtime errors.
Note: using dynamic
type for Map<>
is considered fine since there is no better way to declare type of JSON payload.
Bad:
dynamic x = 10; // LINT
// LINT
String concat(dynamic a, dynamic b) {
return a + b;
}
Good:
int x = 10;
final x = 10;
String concat(String a, String b) {
return a + b;
}
