dart
dependencies:
flutter:
sdk: flutter
masked_text_field: any
import flutter_social_button.dart
import 'package:masked_text_field/masked_text_field.dart';
It's very simple, it's a Widget as all the other ones.
MaskedTextField
(
maskedTextFieldController: textfieldController,
mask: "xxx.xxx.xxx.xxx",
maxLength: 15,
keyboardType: TextInputType.number,
inputDecoration: new InputDecoration(
hintText: "192.192.192.192",
counterText: "",
labelText: "IP Address"),
);
'x' is the normal char that your text will have.
this sample reproduces something like this in the end: 192.192.192.192.
You can also change the escape character you want to use.
If you want to change it, you just need to fill the property escapeCharacter with the character you want.
MaskedTextField
(
maskedTextFieldController: textfieldController,
escapeCharacter: '#',
mask: "###.###.###.###",
maxLength: 15,
keyboardType: TextInputType.number,
inputDecoration: new InputDecoration(
counterText: "",
hintText: "192.192.192.192",
labelText: "IP Address"),
);
'x' is the default escape character.
