sourcepoint unified cmp - flutter inappwebview extension

This is integrating the flutter integration for sourcepoint's unified CMP with the flutter_inappwebview package. This package provides a single extension method preloadConsent() to the InAppWebViewController to inject the consent given in "flutter land" into the inappwebview.

Contributing to the project

Please the CONTRIBUTING.md for details.

example usage:

In order to use this extension please make sure to implement sourcepoint_unified_cmp in your project - for further tasks please check the sourcepoint_unified_cmp package.

sample code:

For a running examples please check the sample app at example/lib/main.dart - the sample app can be run using melos run run:example:flutter_inappwebview -- -d sdk (android) or melos run run:example:flutter_inappwebview -- -d IPhone (ios).

Important bits of the implementation are:

Import the sourcepoint unified cmp and the flutter_inappwebview package and the extension to the webview

import 'package:flutter_inappwebview/flutter_inappwebview.dart';
import 'package:sourcepoint_unified_cmp/sourcepoint_unified_cmp.dart';
import 'package:sourcepoint_unified_cmp_flutter_inappwebview_extension/sourcepoint_unified_cmp_flutter_inappwebview_extension.dart';

Initialize and configure the sourcepoint controller

    final config = SPConfig(
      accountId: 22,
      propertyId: 31007,
      propertyName: 'sdks-auth-consent-test-page',
      pmId: '122058',
      campaigns: [CampaignType.gdpr],
    );

    _controller = SourcepointController(config: config)
      ..setEventDelegate(
        SourcepointEventDelegate(
          onConsentReady: (SPConsent consent) {
            debugPrint('DELEGATE onConsentReady: Consent string: '
                '${consent.gdpr?.euconsent}');
          },
          onSpFinished: (SPConsent consent) {
            debugPrint(
              'DELEGATE SpFinished: Consent string: ${consent.gdpr?.euconsent}',
            );
          },
        ),
      );

Once a site is loaded in the webview, the consent can be injected using the preloadConsent() method on the InAppWebViewController - consent has to be obtained before using the sourcepoint unified cmp package.

return InAppWebView(
  initialUrlRequest: URLRequest(
    url: WebUri(
      'https://sourcepointusa.github.io/sdks-auth-consent-test-page/?_sp_version=4.9.0&_sp_pass_consent=true',
    ),
  ),
  onWebViewCreated: (controller) {
    _webViewController = controller;
  },
  onLoadStop: (controller, url) async {
    await _webViewController.preloadConsent(consent: consent!);
  },
);

Important: the web page needs to implement the sourcepoint unified cmp script and the ?_sp_version=4.9.0&_sp_pass_consent=true has to be used in order to instruct the js sdk to listen for external consent.
