Create flutter wrapper package for native SDK

Hello, We are looking for a flutter, kotlin/java and objective-c/swift expert, that can create a flutter wrapper package around an existing AD SDK. We have 2 native SDKs (an Android and an iOS Version), that need to be implemented into a flutter application. Because the SDK not only uses PlatformChannels, but also native Views (it shows AdBanners), we will need to implement NativeViews: [login to view URL] Attached you will find the SDK (Documentation PDF, Lib Files and Examples for iOS and Android). ## Flutter functionality we need The following SDK functionality should be abstracted and implemented in the final package. The numbers in brackets reference the katalognumbers in the documentation PDF. ### **SDK methods to forward to flutter:** (should just be callable in Flutter and return the data - simple Platform Channels) * isOptedOut Method (11.1) * optOut Method (11.1) * optIn Method (11.1) * indicateGdpr (11.2) * dontTrack (11.4) ### **AdBanner widget** We want to be able to show an AdBanner using the following Widget Call: ```dart AdBanner( // base config networkId: 0000, // our adnetwork id for the application - is passed in 5.2 übergeben contentUnitId: 001010, // the specific ad placement position - the specific ad is passed in 5.2 übergeben // configuration debug: true, // 13.2 or 13.1 tcfString: '4j3hfdsja8sfudsfajfdskjdfs9jfdsdsfjdsfa', // 11.3 = iab Consent string for ad customization (will be fetched from the consent management plattform externally and passed here) ) ``` ## Acceptance criteria: * We can show AdBanners using a network, contentId, debug and tcfString (see above) * All Banners render correctly * All the methods above (see above) work and respect the values * Works on iOS and Android by just adding it to pubspec and using the widget * The package is well implemented and documented
