+# sms_autofill
+
+Flutter plugin to provide SMS code autofill support. 
+
+For iOS, this package is not needed as the SMS autofill is provided by default, but not for Android, that's where this package is useful.
+
+No permission to read SMS messages is asked to the user as there no need thanks to SMSRetriever API. 
+
+## Usage
+You have two widgets at your disposable for autofill an SMS code, PinFieldAutoFill and TextFieldPinAutoFill.
+
+Just before you sent your phone number to the backend, you need to let know the plugin that it need to listen for the SMS with the code.
+
+To do that you need to do:
+
+```dart
+await SmsAutoFill().listenForCode;
+```
+This will listen for the SMS with the code during 5 minutes and when received, autofill the following widget.
+
+### PinFieldAutoFill
+```dart
+PinFieldAutoFill(
+ decoration: // UnderlineDecoration, BoxLooseDecoration or BoxTightDecoration see https://github.com/TinoGuo/pin_input_text_field for more info,
+ currentCode: // prefill with a code
+ onCodeSubmitted: //code submitted callback
+ onCodeChanged: //code changed callback
+ codeLength: //code length, default 6
+ ),
+```
+
+
+### TextFieldPinAutoFill
+```dart
+TextFieldPinAutoFill(
+ decoration: // basic InputDecoration
+ currentCode: // prefill with a code
+ onCodeSubmitted: //code submitted callback
+ onCodeChanged: //code changed callback
+ codeLength: //code length, default 6
+ ),
+```
+
+### Android SMS constraint
+For the code to be receive, it need to follow some rules as describe here: https://developers.google.com/identity/sms-retriever/verify
+- Be no longer than 140 bytes
+- Begin with the prefix <#>
+- Contain a one-time code that the client sends back to your server to complete the verification flow
+- End with an 11-character hash string that identifies your app
+
+One example of SMS would be: 
+```
+<#> ExampleApp: Your code is 123456
+FA+9qCX9VSu
+``` 
+
+## Helper
+
+### PhoneFieldHint [Android only]
+PhoneFieldHint is a widget that will allow you ask for system phone number and autofill the widget if a phone is choosen by the user.
+
+
+### Custom CodeAutoFill 
+If you want to create a custom widget that will autofill with the sms code, you can use the CodeAutoFill mixin that will offer you:
+
+- `listenForCode()` to listen for the SMS code from the native plugin when SMS is received, need to be called on your `initState`.
+- `cancel()` to dispose the subscription of the SMS code from the native plugin, need to be called on your `dispose`.
+- `codeUpdated()` called when the code is received, you can access the value with the field `code`.
