derivePath method
Derives a new HDNode from this instance based on the path
Implementation
HDNode derivePath(String path) {
List<String> splitPath = path.split('/');
if (splitPath[0] == 'm') {
splitPath = splitPath.sublist(1);
}
return splitPath.fold(this, (HDNode prevHd, String indexStr) {
int index;
if (indexStr.endsWith("'")) {
index = int.parse(indexStr.substring(0, indexStr.length - 1));
return prevHd._deriveHardened(index);
} else {
index = int.parse(indexStr);
return prevHd.derive(index);
}
});
