Usage #
To identify visitors, you need a Fingerprint Pro account (you can sign up for free).
Go to the Fingerprint Pro dashboard.
Navigate to App Settings > API Keys to find your Public API Key.
1. Configure the plugin #
import 'package:fpjs_pro_plugin/fpjs_pro_plugin.dart';
// ...
// Initialization
class _MyAppState extends State<MyApp> {
@override
void initState() {
super.initState();
doInit();
}
void doInit() async {
await FpjsProPlugin.initFpjs(
'<apiKey>' // insert your actual API key here
);
}
// ...
}

You can also configure region, endpoint and endpointFallbacks in the initFpjs method, like below. For the web platform, you can use an additional scriptUrlPattern and scriptUrlPatternFallbacks properties to specify a custom URL for loading the JavaScript agent. This is required for proxy integrations.
void doInit() async {
await FpjsProPlugin.initFpjs(
'<apiKey>',
endpoint: 'https://subdomain.domain.com',
endpointFallbacks: ['https://subdomain2.domain.com', 'https://subdomain3.domain.com'],
region: Region.eu, // or Region.ap, Region.us
// Only necessary for the web platform
scriptUrlPattern: 'https://your.domain/fp_js/script_path?apiKey=<apiKey>&version=<version>&loaderVersion=<loaderVersion>',
scriptUrlPatternFallbacks: ['https://your.second-domain/fp_js/script_path?apiKey=<apiKey>&version=<version>&loaderVersion=<loaderVersion>']
);
}

2. Use the plugin in your application code to identify a visitor #
2.1 Use the getVisitorId method if you only need a visitorId:
import 'package:fpjs_pro_plugin/fpjs_pro_plugin.dart';
// ...
// Initialization
class _MyAppState extends State<MyApp> {
// ...
// Usage
void identify() async {
try {
visitorId = await FpjsProPlugin.getVisitorId() ?? 'Unknown';
// use the visitor id
} on FingerprintProError catch (e) {
// process an error somehow
// check lib/error.dart to get more info about error types
}
}
}
copied to clipboard
2.2 Use getVisitorData to get extended result
import 'package:fpjs_pro_plugin/fpjs_pro_plugin.dart';
// ...
// Initialization
class _MyAppState extends State<MyApp> {
// ...
// Usage
void identify() async {
try {
deviceData = await FpjsProPlugin.getVisitorData();
// use the visitor id
} on FingerprintProError catch (e) {
// process an error somehow
// check lib/error.dart to get more info about error types
}
}
}
copied to clipboard
By default getVisitorData() will return a short response with the FingerprintJSProResponse type.
Provide extendedResponseFormat=true to the initFpjs function to get extended result of FingerprintJSProExtendedResponse type.
void doInit() async {
await FpjsProPlugin.initFpjs('<apiKey>', extendedResponseFormat: true);
}

Linking and tagging information #
The visitorId provided by Fingerprint Identification is especially useful when combined with information you already know about your users, for example, account IDs, order IDs, etc. To learn more about various applications of the linkedId and tag, see Linking and tagging information.
void identify() async {
const tags = {
userAction: 'login',
analyticsId: 'UA-5555-1111-1'
};
const linkedId = 'user_1234';
visitorId = await FpjsProPlugin.getVisitorId(linkedId: linkedId, tags: tags);
deviceData = await FpjsProPlugin.getVisitorData(linkedId: linkedId, tags: tags);
}
