BloomCrashFingerprint class

Utilities for calculating deterministic crash grouping fingerprints.

Normalizes dynamic data (UUIDs, hex addresses, numeric IDs) and extracts user-space stack frames to group identical root-cause errors together in telemetry backends.

Example:

final tokens = BloomCrashFingerprint.compute(
  exceptionType: 'FormatException',
  message: 'Invalid UUID: 123e4567-e89b-12d3-a456-426614174000',
);
final hash = BloomCrashFingerprint.hashTokens(tokens);

Static Methods

compute({required String exceptionType, required String message, String? stackTrace, List<String>? customFingerprint}) → List<String>

Computes a deterministic list of fingerprint tokens and SHA-256 hash.

hashTokens(List<String> tokens) → String

Calculates a SHA-256 hex string from the fingerprint tokens.

sanitizeMessage(String message) → String

Normalizes dynamic tokens (UUIDs, hex addresses, integers) in error messages.
