159-166: 💤 Low valueConsider narrowing the random factor range for quiz consistency.
The option-generation logic uses a wide random factor range (30%–170% via
0.3 + random.nextDouble() * 1.4on line 159, plus conditional swaps). This can produce very easy or very hard rounds unpredictably. Tightening the range or using fixed difficulty tiers would improve quiz balance.🤖 Prompt for AI Agents

In `@lib/screens/home/currency_quiz.dart` around lines 159 - 166, The random factor range in the factors array initialization is too wide (from 0.3 to 1.7 or 30%-170%), which combined with the conditional factor modifications, produces unpredictable quiz difficulty. Narrow the range for the random multiplier in the expression `0.3 + random.nextDouble() * 1.4` by reducing the coefficient (currently 1.4) to a smaller value, or replace the random logic with fixed difficulty tiers to ensure consistent quiz balance across rounds. This affects the factors array setup and the random.nextDouble() multiplication.

In `@lib/l10n/app_en.arb`:
- Around line 152-183: The quiz-related localization strings have been added to
lib/l10n/app_en.arb but the generated Dart localization file
lib/l10n/app_localizations_en.dart is out of sync, causing a 25-entry mismatch
between the ARB source and the generated output. Run the command flutter
gen-l10n from the project root to regenerate the localization files and ensure
lib/l10n/app_localizations_en.dart reflects all the new quiz keys and methods.
In `@lib/screens/home/currency_quiz.dart`:
- Around line 179-187: The duplicate-removal loop in the currency_quiz.dart file
(the while loop checking options.toSet().length < options.length) can become
infinite when the rounding operation in _roundReadableAmount repeatedly produces
the same values, especially for zero-decimal currencies. Add an iteration limit
counter to the while loop to break after a maximum number of attempts (e.g., 10
iterations), and implement a fallback strategy when the limit is reached—such as
manually generating unique values using fixed percentage offsets (like 0.95x,
1.05x, 1.15x of the correctAmount) instead of relying solely on the random
range, or using a while-true loop with a max attempts check that throws an error
or uses a predefined set of alternatives if duplicates persist.

179-188:⚠️ Potential issue | 🟠 Major | ⚡ Quick winAdd a deterministic fallback when the retry cap is hit.
The loop is bounded now, but it can still return duplicate numeric options. In multiple-choice mode that leaves identical answer tiles on screen, and because correctness is checked by value equality, duplicated values are effectively scored as the same answer.
♻️ Suggested direction
var cycleCount = 0; while (options.toSet().length < options.length && cycleCount++ < 10) { var duplicateIndex = options.indexWhere( (option) => options.where((other) => other == option).length > 1, ); options[duplicateIndex] = _roundReadableAmount( correctAmount * (0.55 + random.nextDouble() * 1.2), currencyId, ); } + if (options.toSet().length < options.length) { + // Fall back to deterministic offsets aligned with the display rounding step + // so the final grid always contains four distinct values. + } return options;🤖 Prompt for AI Agents
