sms_autofill #

pub package 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:

await SmsAutoFill().listenForCode;

This will listen for the SMS with the code during 5 minutes and when received, autofill the following widget.

PinFieldAutoFill #


                decoration: // UnderlineDecoration, BoxLooseDecoration or BoxTightDecoration see for more info,
                currentCode: // prefill with a code
                onCodeSubmitted: //code submitted callback
                onCodeChanged: //code changed callback
                codeLength: //code length, default 6

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:

  • 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
