case_block_not_terminated
The last statement of the 'case' should be 'break', 'continue', 'rethrow', 'return', or 'throw'.
Description
#The analyzer produces this diagnostic when the last statement in a case
block isn't one of the required terminators: break
, continue
, rethrow
, return
, or throw
.
Example
#The following code produces this diagnostic because the case
block ends with an assignment:
dart
void f(int x) {
switch (x) {
case 0:
x += 2;
default:
x += 1;
}
}
Common fixes
#Add one of the required terminators:
dart
void f(int x) {
switch (x) {
case 0:
x += 2;
break;
default:
x += 1;
}
}
