Validate the diagnostic
Confirm the reported code matches this rule before you edit it.
Confirm the reported code matches react-doctor/rn-reanimated-4-no-legacy-spring-thresholds. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.
Compare the code
The corrected pattern shows a focused way to address the diagnostic.
Reported pattern
import { withSpring } from "react-native-reanimated";
withSpring(target, {
restDisplacementThreshold: 0.01,
restSpeedThreshold: 0.01,
});Corrected pattern
import { withSpring } from "react-native-reanimated";
withSpring(target, {
energyThreshold: 0.001,
});How to fix
Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.
Copyable fix prompt
Copy this self-contained prompt into your coding agent after you confirm the diagnostic.
Fix every confirmed
Reference transformation:Before:react-doctor/rn-reanimated-4-no-legacy-spring-thresholds diagnostic in the current repository.
Required change:
- Replace Reanimated 3 rest thresholds with Reanimated 4's energyThreshold spring option.import { withSpring } from "react-native-reanimated";
withSpring(target, {
restDisplacementThreshold: 0.01,
restSpeedThreshold: 0.01,
});import { withSpring } from "react-native-reanimated";
withSpring(target, {
energyThreshold: 0.001,
});Constraints:
- Confirm the reported code matches the Before pattern.
- Make the smallest change that fixes the root cause.
- Preserve behavior and interfaces unrelated to this diagnostic.
- Reuse existing project components, utilities, and conventions.
- Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations.
- Adapt identifiers and framework details instead of copying blindly.
- Do not disable the rule or suppress matching code.
- Confirm this rule is enabled for the project:
reanimated:4.
Verification:
- Run focused tests for the changed behavior.
- Run React Doctor and confirm this diagnostic no longer appears.
- Report the files changed and any checks you could not run.Related rules
