fix value update

[tainanfochesatto]

The new value is currently being updated before the minimum and maximum check, causing issues when obtaining the current value through the methods getDouble(), getUnformattedValue() and getFormattedValue() after exceeding the maximum value.

Sample code

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final formatter = CurrencyTextInputFormatter.simpleCurrency(maxValue: 100);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Padding(
        padding: const EdgeInsets.all(32.0),
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text('Updated Value:'),
            Text(
              '${formatter.getDouble()}',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
            TextField(
              inputFormatters: [formatter],
              keyboardType: TextInputType.number,
            ),
            ElevatedButton(
              onPressed: () => setState(() {}),
              child: const Text('Update value'),
            ),
          ],
        ),
      ),
    );
  }
}```
