In the pubspec.yaml
of your flutter project, add the following dependency:
dependencies:
...
flutter_snake: any
In your library add the following import:
import 'package:flutter_snake/flutter_snake.dart';
For help getting started with Flutter, view the online documentation.
First, define the SnakeGame
:
SnakeGame? snakeGame;
@override
void initState() {
super.initState();
// Example:
snakeGame = new SnakeGame(
caseWidth: 25.0,
numberCaseHorizontally: 11,
numberCaseVertically: 11,
durationBetweenTicks: Duration(milliseconds: 400),
colorBackground1: Color(0XFF7CFC00),
colorBackground2: Color(0XFF32CD32),
);
}
Then, add the snakeGame
in your page:
@override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: snakeGame ?? Text("Not initialized"),
),
);
}
The snake will start, but he will crash into the wall because we didn't implemented his movement.
For example, you can manage his movement like this :
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
IconButton(
onPressed: () => snakeGame?.nextDirection = SNAKE_MOVE.left, // Define left as the next direction of the snake
icon: Icon(Icons.subdirectory_arrow_left),
),
Text("SNAKE"),
IconButton(
onPressed: () => snakeGame?.nextDirection = SNAKE_MOVE.right, // Define right as the next direction of the snake
icon: Icon(Icons.subdirectory_arrow_right),
),
],
),
You can also add a controller
to the snakeGame
so you can listen to the GameEvent
(win, loose, food eaten)
StreamController<GAME_EVENT>? controller;
SnakeGame? snakeGame;
@override
void initState() {
super.initState();
controller = StreamController<GAME_EVENT>();
controller?.stream.listen((GAME_EVENT value) {
print(value.toString());
});
snakeGame = new SnakeGame(
caseWidth: 25.0,
numberCaseHorizontally: 11,
numberCaseVertically: 11,
controllerEvent: controller,
durationBetweenTicks: Duration(milliseconds: 400),
colorBackground1: Color(0XFF7CFC00),
colorBackground2: Color(0XFF32CD32),
);
}
@override
void dispose() {
controller?.close();
super.dispose();
}
/// Case width / height (It's a square)
double caseWidth;
/// Duration between each ticks
final Duration durationBetweenTicks;
/// Number of case horizontally (x)
final int numberCaseHorizontally;
/// Number of case vertically (y)
final int numberCaseVertically;
/// If defines, the controller stream receive the game event
final StreamController<GAME_EVENT>? controllerEvent;
/// Color variation for the background
final Color colorBackground1;
final Color colorBackground2;
/// Snake image body and fruit
final String? snakeHeadImgPath;
final String? snakeBodyImgPath;
final String? snakeBodyTurnImgPath;
final String? snakeTailImgPath;
final String? snakeFruitImgPath;
