The AerosyncSDKPage widget takes in a env parameter, a token parameter a style parameter deeplink, 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.

The Style parameter takes in a Map<String, String> object with width, height, and bgColor parameters that will customize the Aerosync widget to your liking. the Map is Required to be sent even if you dont want to change one of the values leave the key out of the map or just all together send an empty map.


📘 The deeplink parameter is a required field that links back to your Flutter application for the best oAuth authentication experience.
The largest FIs in the US use oAuth experiences to authenticate their end user's banks for the optimal user experience in a secure manner.
To implement deeplinking using Flutter please refer to the official Flutter Deeplink guide here.

Store connected account #
Store onSuccess() data attributes to authenticate with the Aerosync API to retrieve account information. The data value returned on the success call is a JSON encoded value so you can decode it as jsonDecode(data) to use it as a Map. Check the given example.
{
"payload": {
"ClientName": "client3",
"user_id": "a2c7f64f-3df9-4090-b3bd-ad6fc3003c90",
"user_password": "735e33b9-78ec-4887-99d7-a3056997ceb9"},
