Usage

Authentication

import 'package:scobro_foundation_flutter/authentication/user_login_screen.dart';

// Use the pre-built login screen
class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: UserLogin(),
    );
  }
}

Layout Components

import 'package:scobro_foundation_flutter/widgets/layout/constrained_centered.dart';

// Create a centered, width-constrained layout
ConstrainedCentered(
  width: 600,
  child: Card(
    child: Padding(
      padding: EdgeInsets.all(16),
      child: Text('Your content here'),
    ),
  ),
)

Loading and Error States

import 'package:scobro_foundation_flutter/widgets/loading_panel.dart';
import 'package:scobro_foundation_flutter/widgets/error_panel.dart';

// Wrap content with loading and error handling
LoadingPanel(
  isLoading: isLoading,
  childBuilder: (context) => ErrorPanel(
    viewModel: viewModel,
    state: state,
    child: YourContent(),
  ),
)

MVVM Framework

import 'package:scobro_foundation_flutter/framework/view_model_bases.dart';

// Create a ViewModel
class MyViewModel extends ViewModelBase<MyViewState> {
  @override
  MyViewState build() => MyViewState();
  
  Future<void> loadData() async {
    await executeOperation(
      () => apiService.getData(),
      (result) => state = state.withData(result),
    );
  }
}

Workflow Components

import 'package:scobro_foundation_flutter/widgets/work_flows/work_flow.dart';

// Create a multi-step workflow
final steps = [
  WorkflowStep(
    id: 'step1',
    title: 'Step 1',
    description: 'First step description',
    shortTitle: 'Step 1',
    contentBuilder: (context) => Step1Content(),
  ),
  // ... more steps
];

WorkflowWidget(
  state: workflowState,
  viewModel: workflowViewModel,
  steps: steps,
)
