Probably only through brute force.
Generate all possible permutations. Then see if they are a valid word period.

hi, how do i set a non-const list as default optional parameter? putting it in the initializer list doesnt work either...
    List<int> list;
    Foo({this.list}): list??=[1,2,3];
Randal L. Schwartz
I don’t think that’s permitted.

sure, but then i still have to make it nullable... i thought i could get around this somehow...

Hi, anyone has managed to use https://github.com/rsocket/rsocket-dart? My RSocket APIs are created using Spring Boot. I get Unhandled Exception: SocketException: Connection refused (OS Error: Connection refused, errno = 111), address =, port = 41582 as error which seems to be related to the Flutter client !! (hence port number)
