A moving marker on a map is the visible part of a location product. The harder decisions concern when the app collects a position, what happens without a connection, and how the person carrying the phone controls that behavior.
My Flutter package BeTracky brings location capture, offline buffering, and server uploads behind a reusable interface. A package can help with implementation, but the product still needs clear requirements.
Decide whether background location is necessary
Does the user need a location only while using a screen, or must a task continue after that screen closes? Those are different requirements. Prefer the least access needed for the actual task.
Android’s background location guidance says background access should be central to the app’s functionality, clearly beneficial, and apparent to the user. Including a location library does not remove those responsibilities from the application.
Define the start and stop controls
Write down what starts a tracking session, what ends it, and how the app shows its current state. Decide what happens when permission is denied or changed. People should be able to understand the relationship between their actions and the information the application collects.
For a field-work product, a useful discovery question is whether location is associated with a specific trip or work session. That is more precise than a requirement to “track users all the time.”
Treat offline behavior as a workflow
If a position is captured without a network connection, should it be discarded, stored locally, or uploaded later? If it is stored, define a retention limit and a retry policy. The backend should also distinguish the time a position was captured from the time it arrived.
BeTracky’s published documentation describes SQLite buffering, uploads, and retry handling. Those capabilities provide building blocks; your product still needs decisions about data ownership, access, and retention.
Agree on a realistic update requirement
More frequent updates can increase resource use. Ask what the business needs to know: a route history, an approximate recent position, or a specific boundary crossing. Then assess the accuracy and frequency needed for that job.
Android documents limits on background location updates. iOS has its own background location model. Avoid promising uninterrupted tracking under every device condition. Validate the intended workflow on the devices and operating-system versions your users actually have.
Questions to include in the scope
- When should tracking run, and how can the user stop it?
- Which features still work if location access is denied?
- How should the app communicate a stale or unavailable position?
- What should happen during a network outage?
- Who can view location records, and for how long?
- Which devices and operating-system versions will be tested?
- What are the release and store-review requirements for this use case?
A precise answer to these questions makes the map more trustworthy. If you are planning a tracking feature, discuss the mobile and backend scope with me.
