Walkthrough

Modified the coin filter dropdown for Trezor mode to source filter options from the current CoinsManagerBloc state instead of the CoinsBloc state. This narrows visible filter options to only coins present in the actively displayed list, reflecting search and test-coin filters applied to the UI.

Changes

Cohort / File(s)	Summary
Trezor Filter Source Update lib/views/wallet/coins_manager/coins_manager_filters_dropdown.dart	Changed _filterTypes for WalletType.trezor to reference bloc.state.coins instead of coinsBloc.state.coins.values; added explanatory comment.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

• Focus on verifying the state source change correctly reflects the intended behavior: filter options now align with the active UI list rather than the complete coin registry
• Confirm the comment accurately describes the logic shift
• Validate that no edge cases arise from the state dependency change (e.g., stale data or race conditions with bloc state updates)

Poem

🐰 A filter finds its perfect home,
No more coins beyond the dome,
What you search is what you see,
Trezor's list, now clear and free! ✨

✅ Passed checks (4 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check	✅ Passed	The PR title "show only compatible activation filter options" accurately captures the main outcome of the code changes. The modification switches the coin existence check source for Trezor mode to display only compatible filter options rather than all available options. The title is concise, specific, and clearly conveys the primary change without being misleading or overly vague.
Linked Issues Check	✅ Passed	The code changes directly address the requirements from issue #2876. The modification to _filterTypes for WalletType.trezor switches the source from coinsBloc.state.coins.values to bloc.state.coins, restricting the displayed filter options to only coins currently visible in the list. This implementation fulfills both stated objectives: reducing the filter options in Trezor mode and ensuring only Trezor-compatible options are shown.
Out of Scope Changes Check	✅ Passed	All changes are directly scoped to the stated objective of reducing filter options in Trezor mode. Only one file is modified with a focused change to the coin filter logic specific to Trezor wallet type. An explanatory comment was added to clarify the logic. No alterations to exported or public entities were made, and no unrelated changes are present outside the scope of issue #2876.
