## Instalation

  ```bash

  $ pub get adler32

  ```

## Usage

  Importing this library exposes the class `Adler32` which contains 3 functions.

### buf

  `int buf(List buf, [int seed])`

  

  The `buf` function takes an array of bytes as the first argument

  ##### Example

  ```dart

  Adler32.buf([65,121,121,32,108,109,97,111,33,33,33]) // 381289312

  ```

### bstr

  `int bstr(String bstr, [int seed])`

  

  The `bstr` function takes a binary string the first argument

  ##### Example

  ```dart

  Adler32.bstr("Ayy lmao!!!") // 381289312

  ```

### str

  `int str(String str, [int seed])`

  

  The `str` function takes a string the first argument

  ##### Example

  ```dart

  Adler32.str("Ayy lmao!!!") // 381289312

  ```

### Using `seed`

All 3 functions take a second optional argument for the starting "seed"

```dart

  int adler32 = Adler32.buf([65, 121, 121]);  // 36766004  "Ayy"

  adler32 = Adler32.str(" lmao", adler32);    // 217907965  "Ayy lmao"

  Adler32.bstr("!!!", adler32);               // 381289312 "Ayy lmao!!!"

```
