ApparenceKit

ApparenceKit is a paid Flutter starter template from the Apparence.io agency. It ships auth, RevenueCat subscriptions, onboarding, notifications, tests and CI/CD, configures Firebase or Supabase automatically, and includes AI coding rules for Cursor-style assistants.

ApparenceKit is a Flutter template for developers who want to start a mobile app from a working foundation instead of rebuilding the same plumbing each time. It comes from Apparence.io, a Flutter agency, and the maker describes it as the internal tool refined across more than 40 production apps before being sold to the public. The kit bundles the features most apps need at launch: authentication, onboarding, in-app subscriptions, push notifications, theming and CI/CD pipelines. In practice, a CLI-driven setup configures a Firebase or Supabase backend automatically, including security, database and authentication, so a running app is promised within about five minutes. Authentication covers email flows (sign in, sign up, password reset), phone login, social logins and a REST API option for teams with their own server. Monetization runs through RevenueCat, with several paywall templates, subscription state checks and ready-made subscription pages for Android and iOS. Notification handling includes device registration, a history page and foreground listeners. The code uses Riverpod for state management and GoRouter for navigation, follows a clean architecture, and ships with unit and widget tests plus GitLab, GitHub and Codemagic templates. The AI angle is a set of custom rules for coding assistants such as Cursor. They describe the kit's architecture, Dart and Flutter practices and testing conventions, so generated code follows the existing patterns. Additional modules include an AI chatbot template that connects to several model providers, home screen widgets for iOS and Android, localization, analytics with Mixpanel and Firebase Analytics, in-app review prompts, feature voting, Meta Pixel integration and a web build target from the same Dart codebase. Access is sold as a one-time lifetime license with a 10-day money-back guarantee, and buyers get a Discord community. Compared with no-code builders like FlutterFlow or Bubble, it hands over full source code and expects Dart skills. Compared with generic web boilerplates, it targets mobile specifically. It suits indie developers, startups and agencies that already know Flutter and want to ship faster.
