api_corrector
Runtime API response validator for Dart & Flutter. Protects apps from malformed or unexpected JSON—even with HTTP 200. A small, lightweight Dart / Flutter package that helps you safely validate API JSON responses at runtime — before they crash your app.
It focuses on what your app expects from the API, not just HTTP status codes.
Why use api_corrector?
Because APIs don’t always behave 😅 Even when the server responds with HTTP 200 OK, the JSON might:
- contain an error payload
- be missing required fields
- return unexpected data types
- partially break due to backend issues This package lets you clearly define what a “valid” response looks like and verifies that the API response actually matches it before your UI touches the data.
If the response doesn’t match your expectations, it fails early and safely.
