The string.dart
file is the part of dart:core
which declares the String
class, so you are using it.
You say that you start the app and that the app hangs. That does not suggest that the analyzer is involved. If the IDE was hanging, that could be related to the analyzer, but a compiled app does not include the analyzer.
That does suggest that it is your code that makes the app hang.
I don't know anything about Flutter widgets, but I can see that your RegExp is most likely wrong.
It collects all non-digits, joins those, and then tries to parse the result as an integer. That will always fall, so the fiction always returns oldValue
.
Try instead:
final withoutSymbols = text.temoveAll(RegExp(r'\D+'));
And see if that helps.

Changing the regex did indeed help 👀 There's probably a Flutter issue that should be filed around that error not being handled/propagated but I'll close this for now. Sorry for the noise!
