Add Support for Fixed Values (Immutable Cells) #3
Description
Description
Enable support for fixed cells—values that the player cannot change. These are the cells pre-filled by the game.
Why
This is essential for puzzles generated by the app. Users should only be able to modify blank cells.
Goals
- Add a fixed flag or state to cells.
- Disable editing or show visual difference (e.g., gray background).
- Prevent accidental changes to fixed values.
Suggested Implementation
- Extend the cell object/class to include a boolean isFixed.
- In the UI, make fixed cells non-editable and styled differently.
