avoid-stream-tostring
Warns when a Stream
is the target of the toString()
invocation or is used in an interpolation.
The result of calling toString()
on a Stream
is Instance of '_ControllerStream<List<String>>'
and is usually not expected.
Example
❌ Bad:
void fn() {
final myStream = Stream.value([1, 2, 3]);
// LINT: Avoid calling 'toString' on 'Stream'.
print(myStream.toString());
// LINT: Avoid calling 'toString' on 'Stream'.
print('hello $myStream');
}
✅ Good:
void fn() {
final myStream = Stream.value([1, 2, 3]);
myStream.listen((value) => print(value));
}
