Validators class

Small, dependency-free validation helpers shared across layers.

Kept intentionally simple: SIMOSEC avoids pulling in external validation/JSON packages so the engine stays lightweight and easy to embed anywhere.

Static Methods

extractAmount(dynamic body) → double?
Extracts a numeric amount from a request body map, checking a few common field names. Returns null if no numeric amount is found.
isEmptyPayload(dynamic value) → bool
Returns true if value is null, an empty string, an empty map, or an empty list/iterable.
isRestrictedAction(String? action, Set<String> restrictedActions) → bool
Returns true if action is present in restrictedActions (case-insensitive).
isStructurallyValidMap(dynamic body) → bool
Returns true if body looks like a well-formed map payload, i.e. it is a Map and every key is a non-empty String.
looksLikeSignature(String? signature) → bool
A minimal signature format sanity check. This does NOT perform real cryptographic verification — see CryptoUtils.verifySignature for that. This just guards against obviously malformed values (empty, too short, whitespace-only).
