SOAP Notes

class SoapNote {
  String subjective, objective, assessment, plan;
  final DateTime date;
  final String patientId;

  SoapNote({required this.patientId, DateTime? date})
    : date = date ?? DateTime.now(),
      subjective = '', objective = '', assessment = '', plan = '';
}

class SoapNoteEditor extends StatefulWidget {
  final String patientId;
  const SoapNoteEditor({super.key, required this.patientId});
  @override State createState() => _SoapNoteEditorState();
}

class _SoapNoteEditorState extends State {
  final _note = SoapNote(patientId: '');
  final _sCtrl = TextEditingController();
  final _oCtrl = TextEditingController();
  final _aCtrl = TextEditingController();
  final _pCtrl = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return SingleChildScrollView(
      padding: const EdgeInsets.all(16),
      child: Column(
        children: [
          _section('Subjective', 'Patient's reported symptoms and history', _sCtrl),
          _section('Objective', 'Vitals, exam findings, lab results', _oCtrl),
          _section('Assessment', 'Diagnosis and differential', _aCtrl),
          _section('Plan', 'Treatment plan, medications, follow-up', _pCtrl),
          const SizedBox(height: 16),
          ElevatedButton.icon(
            onPressed: () => /* encrypt and save */,
            icon: const Icon(Icons.lock),
            label: const Text('Save & Encrypt'),
          ),
        ],
      ),
    );
  }

  Widget _section(String title, String hint, TextEditingController ctrl) {
    return Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        Text(title, style: const TextStyle(fontWeight: FontWeight.bold, fontSize: 16)),
        const SizedBox(height: 4),
        TextField(controller: ctrl, maxLines: 3,
          decoration: InputDecoration(hintText: hint, border: const OutlineInputBorder())),
        const SizedBox(height: 16),

UI & UX Suggestions

Use a clean white, blue accent for interactive elements, red for critical flags colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
