class Hash_Password extends StatefulWidget {
@override
_Hash_PasswordState createState() => _Hash_PasswordState();
}

class _Hash_PasswordState extends State<Hash_Password> {

TextEditingController _controller = TextEditingController();
//Trigger for generating the hash code for the entered password
bool password_hash_trigger = false;
bool visible = true;

@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
appBar: AppBar(
title: Text(
'Hash Password',
style: TextStyle(fontWeight: FontWeight.bold,fontSize: 25),
),
),

body: Column(

children: <Widget>[
Password_Hasher(
algorithm_number: '256',
Hex: true,
controller: _controller,
restrict: true,
restrict_number: 10,

child: TextFormField(
controller: _controller,
decoration: InputDecoration(
hintText: 'Enter Password Here!',
),
style: TextStyle(fontSize: 20,fontWeight: FontWeight.bold),
onChanged: (String newValue){
//Do something with the user input.
},
),
),

SizedBox(height: 15.0,),

TextButton(

setState(() {
password_hash_trigger = true;

Hashing Algorithms: algorithm_number property specify the number afetr SHA for specifying an algorithm to produce hashcode for the password entered.
Number System: Base58, Base64, Hex are bool properties which specify the Number System for the hash code (Note: only one of these is needed to be specified as true, Hex is true by default, if multiple number systems sre set true, then it may result to unwanted outcomes)
Character Restriction: In case there is restriction on number of characters to be entered for the password, set restrict as true, and then, specify the number of characters allowed using restrict_number property.
trigger: it is a bool property which specifies when to convert entered text to its corresponding hashcode.
child: it is the child property of Password_Hasher() widget, it takes TextFormField, in which password is supposed to be entered.
controller: it takes the TextEditingController of the child TextFormField as input.
