formatWithMask method
Inspired from Vincent van Proosdij.
Formats the String
with a specific mask.
You can assign your own specialChar
, defaults to '#'.
Example
var string3 = 'esentisgreece';
var mask3 = 'Hello ####### you are from ######';
var masked3 = string3.formatWithMask(mask3); // returns 'Hello esentis you are from greece'
Implementation
String? formatWithMask(String mask, {String specialChar = '#'}) {
if (this.isBlank) {
return this;
}
//var buffer = StringBuffer();
var maskChars = mask.toArray;
var index = 0;
var out = '';
for (var m in maskChars) {
if (m == specialChar) {
if (index < this!.length) {
out += this![index];
index++;
}
} else {
out += m;
}
}
return out;
}
