firstToUpper method
Converts first character in this string to upper case.
If the first character of the string is already in upper case,
this method returns this
.
Example:
'alphabet'.firstToUpper(); // 'Alphabet'
'ABC'.firstToUpper(); // 'ABC
This function uses toUpperCase()
, that uses
the language independent Unicode mapping and thus only
works in some languages.
Implementation
String firstToUpper() =>
isNotEmpty ? '${this[0].toUpperCase()}${substring(1)}' : this;
