dart - Removing empty lines while reading a file in Dartlang -


i have file like:

a b   c d

both readaslines() , readasstring() + string.split('\n') give me:

[a, b, , , c, d]

what smartest way get?

[a,b,c,d]

one possibility be:

import 'dart:io';  main() {   file f = new file('test.txt');   f.readaslines().then((list<string> lines) {     print(lines.where((string s) => s.isnotempty));   }); }
