Installation

flutter pub get tilecode

Usage

import 'package:tilecode/tilecode.dart';

// encode hex,binary tilecode to string
print(TileCode(zoom: 10, x: 3, y: 10).toHexString(true)); // 0x0004e
print(TileCode(zoom: 10, x: 3, y: 10).toBinaryString(true)) // 0b00000000000001001110

// decode hex,binary tilecode from string
final tilecodeByHex = TileCode.fromHexString("0x0004e");
final tilecodeByBinary = TileCode.fromHexString("0b");

// get start/center location of the tile
final tileStart = TileCode(zoom: 10, 3, 10).getLocationStart(); // 84.73838712095339,-178.9453125
final tileCenter = TileCode(zoom: 10, 3, 10).getLocationCenter(); // 84.7222427259026,-178.76953125
