Getting started

import the fischerandom_chess class

import 'package:fischerandom_chess/fischerandom_chess.dart' 

Usage

• Generates a random starting position, returning its ID and arrangement of pieces.

FischerRandomLookUp fischerRandomLookUp = FischerRandomLookUp();
Map<String, dynamic> random = fischerRandomLookUp.random();

• Picks a random starting position's ID.

FischerRandomLookUp fischerRandomLookUp = FischerRandomLookUp();
Map<String, dynamic> random = fischerRandomLookUp.randomID();

• Get the starting position's arrangement of pieces by a given ID

FischeRandomChess fischeRandomChess = FischeRandomChess();
ind id=10; //example
var result = fischerRandomLookUp.decode(id);
if(result==false){
 //not a valid id
}else if(result is List<String>){
 print(result);
}

• Get the starting position's arrangement of pieces by a given ID

FischeRandomChess fischeRandomChess = FischeRandomChess();
String arrangments = 'NBBQNRKR'; // or ['N','B','B','Q','N','R','K','R']
var result random = fischerRandomLookUp.encode(arrangments);
if(result==false){
 //not a valid id
}else if(result is int){
 print(result);
}
