Unify Obsessions and Compulsions in Tracking

[menaechmi]

To track an event, the app requires users to separately log obsessions and compulsions, but this doesn't reflect the many-to-many relationship of these actual events, and duplicates the questions a user must answer for a single event.

Here's the current code:

patterns/lib/screens/ocd_tracker_screen.dart

Lines 746 to 782 in 110e05f

	const SizedBox(height: 32),
	SegmentedButton<OcdType>(
	style: SegmentedButton.styleFrom(
	selectedBackgroundColor: theme.colorScheme.primary.withOpacity(
	0.1,
	),
	selectedForegroundColor: theme.colorScheme.primary,
	side: BorderSide(color: theme.dividerColor),
	),
	segments: const [
	ButtonSegment(
	value: OcdType.obsession,
	label: Text('Obsession'),
	icon: Icon(LineIcons.brain),
	),
	ButtonSegment(
	value: OcdType.compulsion,
	label: Text('Compulsion'),
	icon: Icon(LineIcons.mouse),
	),
	],
	selected: {_type},
	onSelectionChanged: (set) => setState(() => _type = set.first),
	),
	const SizedBox(height: 32),
	TextField(
	controller: _contentController,
	decoration: InputDecoration(
	labelText: _type == OcdType.obsession
	? 'What did the thought say?'
	: 'What was the urge?',
	hintText: _type == OcdType.obsession
	? 'Name the thought or image.'
	: 'Name the urge or compulsion.',
	),
	maxLines: 3,
	),

The current implementation uses a segmented button that changes the first question presented to the user ("What did the thought say?" if OcdType == obsession, "What was the urge?" otherwise).

I suggest presenting both questions to the user and replacing the text boxes with unordered lists that the user can fill in, like in this mock-up:

This would allow for better tracking (compulsion X is strongly correlated with obsession Y) and be easier on users (one report vs at least two; reduce duplicated questions).
