June 19, 2016Dart Doesn't Have StringBuffer.replace, Is There a Workaround?
You could do this: extension on StringBuffer { void replace(int start, int end, String replacement) { final old = toString(); clear(); if (start > 0) write(old.substring(0, start)); write(replacement); if (end < old.length) write(old.substring(end)); } } In Dart, a StringBuffer is a stream-like StringSink and not actually backed by a char[] as in Java. But it's not 1995 anymore and computers are fast and can create temporary strings faster. So just create temporary strings, hoping that Dart will internally do something more clever for substring as simply creating new copies. More on reddit.com
