sprintf method
Formats arguments into a String according to format.
Supports the full C99 format specifier syntax — see printf for details.
Example:
stdc.sprintf("%05d", [42]); // "00042"
stdc.sprintf("%.3e", [12345.6789]); // "1.235e+04"
stdc.sprintf("%-10s|", ["hello"]); // "hello |"
Implementation
String sprintf(String format, [List<dynamic> args = const []]) {
final ap = va_start(args);
final result = vsprintf(format, ap);
va_end(ap);
return result;
}
