Introduction

This Flutter SDK provides an interface to load Aerosync-UI in Flutter apps through flutter_inappwebview. Securely link your bank account through your bank’s website. Log in with a fast, secure, and tokenized connection. Your information is never shared or sold.

1. Installation

1. First add aerosync_flutter_SDK as a dependency to the pubspec.yaml file.

2. Import the library

  import 'package:aerosync_flutter_SDK/aerosync_flutter_SDK.dart';

2. Usage/Examples

The Aerosync plugin is brought in as a separate window that launches the Flutter InAppWebView Plugin with the aerosync starting url.
In this example the widget is navigated to when ElevatedButton is pressed.

...  
@override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: isLoading
            ? LaunchButton(env: _env, token: _token)
            : SizedBox(), // this includes all the button and functionality
      ),
    );
  }
...

class LaunchButton extends StatelessWidget {
  var env;
  var token;
  LaunchButton({Key? key, required this.env, required this.token})
      : super(key: key);

  // handle the OnEvent callback from aerosync
  handleOnEventAerosync(eventType, data) {
    print("CALLBACK FULLY HANDLED: OnEvent");
  }

  // handle the OnSuccess callback from aerosync
  handleOnSuccessAerosync(eventType, data) {
    print("CALLBACK FULLY HANDLED: OnSuccess");
  }

  // handle the OnClose callback from aerosync
  handleOnCloseAerosync(eventType, data) {
    print("CALLBACK FULLY HANDLED: OnClose");
  }

  // handle the OnLoad callback from aerosync
  handleOnLoadAerosync(eventType, data) {
    print("CALLBACK FULLY HANDLED: OnLoad");
  }

  // handle the OnError callback from aerosync
  handleOnErrorAerosync(eventType, data) {
    print("CALLBACK FULLY HANDLED: OnError");
  }

  @override
  Widget build(BuildContext context) {
    return SafeArea(
        child: Column(
      mainAxisAlignment: MainAxisAlignment.center,
      mainAxisSize: MainAxisSize.min,
      children: [
        ElevatedButton(
          onPressed: () => {
            Navigator.of(context).push(MaterialPageRoute(
                builder: (context) => AerosyncSDKPage(
                      env: env,
                      token: token,
                      onEvent: handleOnEventAerosync,
                      onSuccess: handleOnSuccessAerosync,
                      onClose: handleOnCloseAerosync,
                      onLoad: handleOnLoadAerosync,
                      onError: handleOnErrorAerosync,
                    )))
          },
          child: Text(
            'Connect',
            style: TextStyle(fontSize: 20),
          ),
        ),
      ],
    ));
  }
}

The AerosyncSDKPage widget takes in a env parameter, a token parameter and callback event notifications needed for your implementation. To generate a token, check out our integration guide here.

Each callback returns an eventType value and data that is returned from aerosync-ui.

Parameter	Type	Description
env	string	Required. Available values: dev, staging, prod.
onEvent	function(response)	Required. This method will be triggered as the user completes the bank link workflow.
onLoad	function(response)	Required. Call function after the contents of webpage have been loaded as the user completes the bank link workflow.
onSuccess	function(response)	Required. This method will be triggered when a bank is added successfully and the user clicks on "continue" button in the final AeroSync-UI page.
onClose	function(response)	Required. This method will be triggered when the aerosync widget is closed.
onError	function(response)	Required. The method is called if AeroSync-UI dispatches any error events.

Store connected account

Store onSuccess() data attributes to authenticate with the Aerosync API to retrieve account information.
