🛠️ Refactor suggestion

Validate input: reject empty orderId upfront.

Prevents constructing/sending malformed events.

   Future<bool> createDispute(String orderId) async {
     try {
+      if (orderId.trim().isEmpty) {
+        _logger.e('Empty orderId, cannot create dispute');
+        return false;
+      }
       _logger.d('Creating dispute for order: $orderId');

New dispute-creation snackbar keys — LGTM; ensure locale parity

Strings read well and the error placeholder is typed. Per guidelines, confirm these keys exist in intl_es.arb and intl_it.arb.

Run to verify presence across locales and metadata health:

🏁 Script executed:

Add admin_npub placeholder metadata for adminTookDisputeUsers
In lib/l10n/intl_en.arb, append the following metadata block:

"@adminTookDisputeUsers": {
  "placeholders": {
    "admin_npub": { "type": "String" }
  }
}
🤖 Prompt for AI Agents 
In lib/l10n/intl_en.arb around lines 294 to 303, the translation key
adminTookDisputeUsers is missing a placeholder metadata block for admin_npub;
add an entry "@adminTookDisputeUsers" with a placeholders object that defines
"admin_npub" of type "String" so the localization tooling recognizes the
placeholder and validates/generated code correctly.
