Selfie and ID Card Capture

This method will capture a selfie and then a ID card image for a tag that may be provided during initiation and if not provided this will be auto generated by the SDK and returned with a code.

Import the library

import 'package:smile_flutter/smile_flutter.dart';

Capture Selfie

If you want the SDK to generate a tag for you then call the method with an empty string

var result = await SmileFlutter.captureSelfieAndIDCard("") ;

If you want the generate to use a custom tag send a string to the SDK with alphanumeric characters with the exception of an underscore and no spacing in them.

var result = await SmileFlutter.captureSelfieAndIDCard(<STRING_TAG>) ;

This will present the two screen as below in the order selfie then id card capture

Get Results

The selfie capture process is an asynchronous process and will return an error code and a tag once done. The result looks as the below

    var resultCode = result!["SID_RESULT_CODE"];
    var resultTag = result["SID_RESULT_TAG"];

�If the result code is -1 AND the tag is not null or empty then the selfie capture was successful.

Optional Permissions

By default the SDK will request for permissions on it's own particularly on android and the first instance the call to the captureSelfie may fail and will definately fail if the user has not allowed the permissions for camera

It is advisable to then do permissions request prior to calling the captureSelfie method to make sure you handle permissions and perhaps even check for permissions before in that case then the call should be

var result = await SmileFlutter.captureSelfieAndIDCard("", HashMap<String, String>(),false)

The false will mean the SDK will try to open the selfie capture and assume permission handling has already been done

Optional UI Customisations

For basic UI customisation, an additional key-value Object needs to be passed as second parameter when performing a call to the library's captureSelfie("<TAG>",HashMap<String, String>(),false)

) method, where tag is a string and config the added key-value Map containing the desired settings.

Selfie Capture Screen Customisation

• capture_title_text: a string value for the selfie capture screen's title. Refer to Strings and Colours section for details.

Selfie Review Screen Customisation

• review_title_text: a string value for the selfie review screen's title.

• review_prompt_text: a string that determines the prompt text view on the selfie review screen; this text view refers to the one directly under the selfie image view

• review_prompt_style: a key-value Object that determines the styling for the prompt text view (the text view directly under the the selfie image view)'s styling - similar to screen_title_style

• review_tip_text: a string used for the tips at the bottom of the selfie capture screen

• review_tip_style: a key-value Object that sets the styling for the tips text view (the text view directly under the prompt text view in the selfie review screen)'s styling - similar to screen_title_style

• review_confirm_text: a string value for the confirm button (positive action)'s text

• review_confirm_color: a 7-character (no alpha channel) hexadecimal color string (ie. #FF0000 for red) that determines the the confirm button's background color

ID Card Capture Screen

• id_capture_side: a string value with options 0,1,2 0 being capture front only, 1 being capture front and back and 2 being capture back only

• id_capture_orientation: a string that determines the prompt text view on the document capture screen; this text view refers to the one directly under the selfie image view

• id_prompt_blurry: a string that determines the prompt text view on the document capture screen whilst the SDK is capturing an image but the image is blurry

• id_prompt_detecting_face: a string that determines the prompt text view on the document capture screen when the SDK has captured a front of id image and facial detection is in progress

• id_prompt_face_detected:a string that determines the prompt text view on the document capture screen when the SDK has captured a front of id image and has detected a face

• id_prompt_fit_id: a string that determines the prompt text view on the document capture screen whilst the SDK is capturing and is the default instruction to the user when all conditions are perfect for capture

• id_prompt_flash_missing: a string that determines the prompt text view on the document capture screen whilst the SDK is capturing an image but there is no sufficient light and no flash light available on the device

• id_prompt_insufficient_light: a string that determines the prompt text view on the document capture screen whilst the SDK is capturing an image but there is no sufficient light

• id_prompt_loading: a string that determines the prompt text view on the document capture screen when the SDK has captured an image and quality checks are in progress

Basic Example

var config = HashMap<String, String>();
config["capture_title_text"] = "Capturing your smile..."";
var result = await SmileFlutter.captureSelfieAndIDCard("", config) ?? null;
