flutter-password-strength's Issues

Only number passwords accepted as best passwords

When user types passwords containing only numbers charsetBonus becomes 1.8, which is higher.

Need to add another control for numbers

if (RegExp(r'^[0-9]*$').hasMatch(password)) {
    charsetBonus = 0.5;
}

add how to use strengthColors to docs.

Hello. I'm trying to change the strengthColors colors. I am unable to do so. Would you be able to add and example to the readme? Thank you.

TweenSequence<Color>([ TweenSequenceItem( weight: 1.0, tween: ColorTween( begin: Theme.of(context).errorColor, end: Theme.of(context).warning, ), ), TweenSequenceItem( weight: 1.0, tween: ColorTween( begin: Theme.of(context).warning, end: Colors.blue, ), ), TweenSequenceItem( weight: 1.0, tween: ColorTween( begin: Colors.blue, end: Theme.of(context) .colorScheme .primary, ), ), ]),

_FlutterPasswordStrengthState#61795(ticker active) was disposed with an active Ticker.

Steps to produce the error

When FlutterPasswordStrength widgets get hidden, this stack trace shows in logs.

Logs

`════════ Exception caught by widgets library ═══════════════════════════════════════════════════════
The following assertion was thrown while finalizing the widget tree:
_FlutterPasswordStrengthState#61795(ticker active) was disposed with an active Ticker.

_FlutterPasswordStrengthState created a Ticker via its SingleTickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. The Ticker must be disposed before calling super.dispose().

Tickers used by AnimationControllers should be disposed by calling dispose() on the AnimationController itself. Otherwise, the ticker will leak.

The offending ticker was: Ticker(created by _FlutterPasswordStrengthState#61795(lifecycle state: created))
The stack trace when the Ticker was actually created was:
