Flutter Mobile Attribution SDK for iOS and Android
See how Airbridge's Flutter SDK tracks attribution and consent-based events on iOS and Android, plus what the Core Plan offers for campaigns and subscriptions.
Key Takeaway
- Airbridge provides a mobile measurement SDK that handles attribution tracking and collects in-app events across both iOS and Android.
- The Core Plan connects paid subscribers and revenue back to specific campaigns while delivering deduplicated attribution across Google, Meta, Apple Search Ads, and TikTok.
- For Flutter apps, the Airbridge Flutter SDK captures user actions as in-app events based on your SDK settings, alongside 25 subscription-optimized standard events in the Core Plan.
When you are building a consumer subscription app in Flutter, your engineering bandwidth is already split between shipping product features and keeping parity across two mobile operating systems. Searching for an official Flutter mobile attribution SDK for iOS and Android usually comes down to a practical question: can you wire up one cross-platform package that reliably tracks where your users come from and what they pay for, without weeks of native bridge debugging? Walking through how the SDK initializes, what campaign metrics it captures, and which ad networks and billing tools connect out of the box will help you decide if this setup fits your stack.
Official Flutter SDK Setup for iOS and Android
If you maintain a single Flutter codebase targeting both the App Store and Google Play, you need to know whether your measurement layer supports both platforms and how much setup work falls on your developers. Airbridge provides a mobile measurement SDK designed to enable attribution tracking and collect in-app events across iOS and Android. Rather than forcing you to rely solely on manual native code for every data stream, the Core Plan bundles mobile SDKs alongside a Web SDK and a Server-to-Server (S2S) API.
Getting the package into your app does not require waiting on an external implementation team. The Airbridge Core Plan uses a self-serve setup and supports AI agent SDK installation through the Airbridge MCP. That option is useful when a lean engineering team wants to move through initialization and configuration steps quickly while keeping developer focus on the core product.
Once your ingestion methods are in place, the Core Plan aggregates your cost and ad spend data, ad revenue, and subscription revenue in one place, while also providing mobile app postbacks for GMAT channels, an audience manager that auto-syncs with ad platforms, and direct report exports to Google Sheets and CSV.
Attribution Measurement Scope for User Acquisition
Counting downloads is rarely enough when your business model depends on recurring billing. You need to see which specific ad creative or keyword actually brings in users who convert past the paywall. Airbridge turns ad spend into revenue by attributing paid subscribers and revenue directly to each campaign.
When you run ads across multiple platforms, each network naturally wants to claim credit for the same user. To prevent double-counting, the Core Plan delivers deduplicated attribution and establishes a single source of truth for each install across its GMAT channels. You get a clearer picture of your attributed installs before deciding where to shift your next week's budget.
For teams bringing users in from mobile web landing pages or managing iOS privacy thresholds, the Core Plan includes a tracking link manager, an API and testing console, and web-to-app attribution. It also covers four-channel ad network attribution, a 24-hour Signal Hold for Meta Ads, and a full set of iOS measurement tools including SKAN 4.0 reporting, a conversion value manager, and SKAN overlap analysis.
Once user acquisition data flows in, you have to evaluate how those cohorts perform over time. The Core Plan provides Revenue, Funnel, Retention, and Cohort reports alongside Predictive LTV and Unattributed Conversion Analysis. If you run search or web campaigns, automated UTM tracking and search ads keyword tracking are also built into the reporting suite.
In-App Event Tracking and Consent in Flutter
Tracking the initial app open is only the first step; knowing what happens inside the app determines whether your acquisition math actually works. The Airbridge Flutter SDK collects app user actions according to the SDK settings you configure and sends them as in-app events.
When you plan your event taxonomy, it helps to follow Airbridge's general SDK implementation guide: identify the specific user actions you need to measure, such as sign-ups and purchases, and place SDK event-tracking calls at those exact points in your code along with relevant parameters like revenue amount or item name.
To save you from inventing every event schema from scratch, the Core Plan provides 25 subscription-optimized standard events, which include Install, Start Trial, Subscribe, Unsubscribe, and Order Complete. Mapping your app flows to these standard events makes it much easier to see where users drop off between their first session and renewal.
Privacy compliance and user consent also dictate when your SDK is allowed to fire events. If your team uses an opt-in policy with the Flutter SDK, events are collected only after the user grants consent. To configure this behavior for an opt-in setup, you should set autoStartTrackingEnabled to false and call startTracking only when event collection is permitted to begin.
Ad Channels and Subscription Tools in the Core Plan
Before committing to an attribution SDK, you should verify that it supports the exact ad networks where you spend your budget and the billing infrastructure that processes your subscriptions. Every extra integration you have to build or maintain yourself costs engineering hours. Here is how channel and third-party coverage works in the Core Plan:
- Four Core Ad Networks (GMAT): The Core Plan supports ad network attribution for Google, Meta, Apple Ads (Apple Search Ads), and TikTok. In our experience documented in our subscription attribution guide, these four channels account for 80–90% of early-stage paid acquisition spend.
- Mobile App Postback Scope: For mobile app postbacks, the Core Plan supports only the Google, Meta, Apple Ads, and TikTok (GMAT) channels.
- Third-Party Subscription Integrations: Alongside the four ad networks, the Core Plan supports integrations with subscription and paywall platforms such as RevenueCat, Adapty, and Superwall.
- Native S2S Subscription Event Flow: The Core Plan features native integrations with RevenueCat and Adapty, allowing subscription events to flow directly into your plan through a Server-to-Server (S2S) connection. Using an S2S connection ensures that trial conversions and renewals are recorded even when the user does not have the app open at the moment of billing.
FAQS
FAQ
How much does the Airbridge Core Plan cost for a small team?
As of October 2026, the Airbridge Core Plan offers a 30-day free trial, then $40+/mo, so you can test the setup with your own app data before paying.
How should we decide if our ad and billing stack fits this setup before integrating?
Start by checking whether your paid acquisition runs on the four supported networks and whether your subscription management tools are on the supported list. Matching your active channels and billing tools upfront prevents you from writing custom bridge code for unsupported platforms later.
When should we choose an opt-in tracking setup for our Flutter app?
If your app serves users in regions that require explicit privacy consent before data collection, configuring the opt-in flow ensures no events fire until the user agrees. You can wire the consent callback directly to your onboarding prompt so measurement starts only after permission is granted.
