The package provides TextInputFormatter for TextField and TextFormField which format the input by a given mask.
Check 'example' folder for code sample
-
Follow the install guide
-
Import the library:
import 'package:mask_text_input_formatter/mask_text_input_formatter.dart';
- Create mask formatter:
var maskFormatter = new MaskTextInputFormatter(mask: '+# (###) ###-##-##', filter: { "#": RegExp(r'[0-9]') });
- Set it to text field:
TextField(inputFormatters: [maskFormatter])
Get masked text:
print(maskFormatter.getMaskedText()); // -> "+0 (123) 456-78-90"
Get unmasked text:
print(maskFormatter.getUnmaskedText()); // -> 01234567890
You can use the updateMask
method to change the mask after the formatter was created:
var textEditingController = TextEditingController(text: "12345678");
var maskFormatter = new MaskTextInputFormatter(mask: '####-####', filter: { "#": RegExp(r'[0-9]') });
TextField(controller: textEditingController, inputFormatters: [maskFormatter]) // -> "1234-5678"
textEditingController.value = maskFormatter.updateMask(mask: "##-##-##-##"); // -> "12-34-56-78"
