Code Review — PR #2249

• Gather context (diff vs origin/develop)
• Review Dart changes (backup_warning_overlay.dart)
• Review localization changes (27 .arb files)
• Validate key consistency across locales
• Post review

Scope note

The diff against origin/develop contains only the backup-warning bullet refactor and the 27 localization files. The transfer-flow items in the PR description (receive-exact-amount for Liquid, insufficient-balance form validation, continue-disabled, split warning boxes) are not present in this diff — they appear to already be on develop. Worth confirming the PR checklist reflects what this branch actually changes.

Findings

1. ⚠️ Medium — Bottom sheet can overflow vertically (no scroll)
lib/features/wallet/ui/widgets/backup_warning_overlay.dart:64-141

The content is a Column(mainAxisSize: MainAxisSize.min) inside Align(bottomCenter) with no scrolling. This refactor grows the content substantially: intro line + 5 bullets (the keystore bullet is long) + a bold closing line + 2 big buttons. On small screens, with large accessibility text scaling, or with longer translations (e.g. German/Arabic keystore strings), this risks a RenderFlex overflow and clipped/unreachable buttons.

Recommend wrapping the text block (or the whole content) in a SingleChildScrollView with Flexible/a max-height constraint so the bullets scroll while the action buttons stay visible.

2. 🟢 Nit — Bullet glyph layout
backup_warning_overlay.dart:94-105

'• ' uses two trailing spaces for indentation. This is fine and RTL is handled automatically by Row Directionality, but a fixed-width leading (SizedBox(width: …)) would give more consistent alignment across font scales/locales than space characters.

Verified ✅

• All 27 locale files contain all 7 new keys (backupWarningDescription, the 5 backupWarningLoseReason* bullets, backupWarningNoRecovery) — checked via grep, 27/27 each.
• No duplicate backupWarningDescription keys after the relocation (the +7/-4 locales moved/retranslated the old key; the +7/-0 locales previously had no value and now do — net improvement).
• Non-English files correctly contain only values (no @-metadata), per the template-only convention; en.arb keeps the @-descriptions.
• Translations are real per-locale strings (not English copies) in spot-checked ar/fr.

Overall

Localization work is clean and consistent. The one substantive concern is the non-scrolling bottom sheet now that the content is much taller — worth addressing before merge to avoid overflow on small/large-text devices.

Note: I can't submit a formal GitHub PR review or true inline comments here — findings are referenced by file:line above.
