Worked on the linagora/tmail-flutter repository to enhance keyboard accessibility within the Email Detail View by implementing an ESC key shortcut to close the view. This feature aligned the email detail interface with the existing composer-close pattern, ensuring a consistent and efficient navigation experience for users who rely on keyboard shortcuts. The solution involved extending the MailViewActionShortcutType enum, updating the AppShortcutManager to map the ESC key, and integrating the logic through the HandleMailShortcutActionsExtension. Utilizing Dart and Flutter for front end development, the work improved user experience by streamlining navigation and supporting accessibility best practices across the mail application.
