📝 WalkthroughWalkthroughUpdated Flutter version pins; added/updated native plugin registrations for Linux, macOS, and Windows; and refactored task database edits so task fields and tags are updated atomically inside a single SQLite transaction. Many files received formatting/whitespace adjustments. Changes

- Line 279: The line assigning taskId uses an unsafe cast (final taskId =
taskMaps.first['id'] as int;) which will throw if id is null; change it to a
null-safe cast and handle the null case explicitly (e.g. final int? taskId =
taskMaps.first['id'] as int?; then either throw a descriptive error like throw
StateError('Missing task id for taskMap: $taskMaps.first') or handle/return a
nullable value as appropriate), and update any downstream code that assumes
taskId is non-null to account for the new nullable type or the explicit error
path.
- Around line 282-301: The current conditional prevents clearing tags because
the txn.delete call is only run when newTags.isNotEmpty; always perform the
delete of the 'Tags' rows for the given task (use the existing txn.delete with
where 'task_uuid = ? AND task_id = ?' and whereArgs [uuid, taskId]) before
inserting any new tags, and then only iterate/insert when newTags contains
non-empty values (preserve the tag.trim().isNotEmpty check) so an empty newTags
list will correctly clear existing tags.

copyWith fallback logic is broken—always evaluates to the parameter, never the current field.
All null-coalescing expressions like dialogBackgroundColor ?? dialogBackgroundColor reference the same parameter name on both sides, so they never fall back to the existing instance values. This makes copyWith unable to preserve current values when only some fields are provided.
The correct pattern is parameterName ?? this.fieldName.
Additionally, purpleShade is missing from the method parameters (lines 31-40), so it cannot be overridden.

Icon doesn't switch during theme transition—consider flipping at midpoint.
icons: icons always uses the starting theme's icon throughout the entire animation. Since IconData can't be interpolated, the standard approach is to switch at t >= 0.5 so the icon flips at the midpoint of the transition rather than staying on the initial value until the animation completes.
💡 Suggested fix

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Add error handling for new exceptions from saveEditedTaskInDB at call sites.
This method now throws when the task is missing or id is null. The only call site (saveTask() at line 240) awaits it without local handling, so failed edits will bubble as unhandled async errors and break UX state after submit. Add try-catch handling in saveTask() or handleWillPop() to gracefully handle these exceptions and provide user feedback.

Description
This PR fixes a data inconsistency issue in the local database when editing tasks.
Previously, task details and associated tags were updated using separate database operations without a shared transaction. This could lead to partial updates if an error or app crash occurred between operations.
