Add to your pubspec.yaml

Usage

See examples in /example folder.

void main() {
  print(Entry.parseLine("30k Sugar").amount);
  print(Entry.parseLineRTL("Sugar 30k").amount);
  // tryParse tries both LTR or RTL in one method call
  print(Entry.tryParse("Sugar 30k").amount);
  print(Entry.tryParse("30k Sugar").amount);
}

The expression is parsed to an instance of the following class

class Entry {
  final String id;
  final String description;
  final double amount;
