How to Make a CRM App with Flutter

Deal Pipeline

class Deal {
  final String id, title, stage, contactId;
  final double value;
  Deal({required this.id, required this.title, required this.stage,
    required this.contactId, required this.value});
}

class PipelineBoard extends StatelessWidget {
  final List stages = ['Lead', 'Qualified', 'Proposal', 'Negotiation', 'Closed'];
  final Map> dealsByStage;

  PipelineBoard({super.key, required this.dealsByStage});

  @override
  Widget build(BuildContext context) {
    return SingleChildScrollView(
      scrollDirection: Axis.horizontal,
      child: Row(
        children: stages.map((stage) {
          final deals = dealsByStage[stage] ?? [];
          return Container(
            width: 260,
            margin: const EdgeInsets.all(8),
            decoration: BoxDecoration(
              color: Colors.grey.shade100,
              borderRadius: BorderRadius.circular(12),
            ),
            child: Column(
              children: [
                Padding(
                  padding: const EdgeInsets.all(12),
                  child: Text(stage, style: const TextStyle(fontWeight: FontWeight.bold)),
                ),
                Expanded(
                  child: ListView(
                    children: deals.map((deal) => Card(
                      child: ListTile(
                        title: Text(deal.title),
                        subtitle: Text('\$\${deal.value.toStringAsFixed(0)}'),
                      ),
                    )).toList(),
                  ),
                ),
              ],
            ),
          );
        }).toList(),
      ),
    );
  }
}

UI & UX Suggestions

Use a blue pipeline, green for closed-won, red for closed-lost 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.
