### Basic Terminal Setup with Controller and View

Source: https://pub.dev/packages/flterm

Set up a TerminalController to manage terminal state and a TerminalView to render it. Connect the controller to your I/O streams.

```dart
import 'package:flterm/flterm.dart';

final controller = TerminalController()
  ..onOutput = (bytes) => pty.write(bytes)
  ..onResize = (cols, rows) => pty.resize(cols, rows)
  ..onBell = playSound;

ptyOutputStream.listen(controller.write);

TerminalView(
  controller: controller,
  theme: TerminalTheme.dark(),
);

```

### Main Application Entry Point

Source: https://pub.dev/packages/flterm/example

This is the main entry point for the flterm example application. It handles web initialization and sets up the main application widget, allowing theme selection.

```dart
import 'package:flterm/flterm.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';

import 'demo_page.dart';
import 'themes.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  if (kIsWeb) {
    await initializeForWeb(
      Uri.parse('assets/assets/libghostty-wasm32-freestanding.wasm'),
    );
  }
  runApp(const _App());
}

class _App extends StatefulWidget {
  const _App();

  @override
  State<_App> createState() => _AppState();
}

class _AppState extends State<_App> {
  var _themeIndex = 0;

  @override
  Widget build(BuildContext context) {
    final entry = TerminalThemes.all[_themeIndex];
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData.dark(),
      home: Scaffold(
        backgroundColor: entry.theme.background,
        body: SafeArea(child: DemoPage(theme: entry.theme)),
        floatingActionButton: Builder(
          builder: (innerContext) => FloatingActionButton(
            onPressed: () => _showThemePicker(innerContext),
            tooltip: 'Theme',
            backgroundColor: Colors.black54,
            foregroundColor: Colors.white,
            child: const Icon(Icons.palette),
          ),
        ),
      ),
    );
  }

  Future<void> _showThemePicker(BuildContext context) {
    final isLarge = MediaQuery.of(context).size.width >= 600;
    if (isLarge) {
      return showDialog<void>(
        context: context,
        builder: (dialogContext) => Dialog(
          child: ConstrainedBox(
            constraints: const BoxConstraints(maxWidth: 360, maxHeight: 480),
            child: _ThemeList(
              currentIndex: _themeIndex,
              onSelect: (i) {
                setState(() => _themeIndex = i);
                Navigator.of(dialogContext).pop();
              },
            ),
          ),
        ),
      );
    }
    return showModalBottomSheet<void>(
      context: context,
      builder: (sheetContext) => SafeArea(
        child: _ThemeList(
          currentIndex: _themeIndex,
          onSelect: (i) {
            setState(() => _themeIndex = i);
            Navigator.of(sheetContext).pop();
          },
        ),
      ),
    );
  }
}

class _ThemeList extends StatelessWidget {
  final int currentIndex;
  final ValueChanged<int> onSelect;

  const _ThemeList({required this.currentIndex, required this.onSelect});

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      shrinkWrap: true,
      itemCount: TerminalThemes.all.length,
      itemBuilder: (_, i) {
        final entry = TerminalThemes.all[i];
        return ListTile(
          leading: Container(
            width: 36,
            height: 36,
            decoration: BoxDecoration(
              color: entry.theme.background,
              borderRadius: BorderRadius.circular(6),
              border: Border.all(color: entry.theme.foreground),
            ),
          ),
          title: Text(entry.name),
          selected: i == currentIndex,
          onTap: () => onSelect(i),
        );
      },
    );
  }
}

```

### flterm Dependency in pubspec.yaml

Source: https://pub.dev/packages/flterm/install

This is an example of how the flterm dependency will appear in your pubspec.yaml file after running `flutter pub add flterm`.

```yaml
dependencies:
  flterm: ^0.0.4
```

--------------------------------

### Import flterm in Dart Code

Source: https://pub.dev/packages/flterm/install

Import the flterm package into your Dart files to start using its terminal widget functionality.

```dart
import 'package:flterm/flterm.dart';
```

--------------------------------

### Initialize WASM Module for Web

Source: https://pub.dev/packages/flterm

On web platforms, initialize the wasm module once before mounting any terminal. This is crucial for web functionality.

```dart
import 'package:flterm/flterm.dart';
import 'package:flutter/foundation.dart';

if (kIsWeb) {
  await initializeForWeb(Uri.parse('assets/libghostty.wasm'));
}

```

--------------------------------

### Configure Link Handling in TerminalView

Source: https://pub.dev/packages/flterm

Configure link detection and activation in the TerminalView. Built-in rules handle OSC 8 metadata, text URLs, and file paths. Custom activation callbacks can be provided.

```dart
TerminalView(
  controller: controller,
  linkSettings: LinkSettings(
    onActivate: (link) {
      if (link.uri case final uri?) openUri(uri);
      if (link.file case final file?) openFile(file);
    },
  ),
);

```

--------------------------------

### Add Custom Link Rules

Source: https://pub.dev/packages/flterm

Add custom regex rules to the LinkSettings for project-specific selectors. Define rules with IDs and patterns, and handle their activation.

```dart
TerminalView(
  controller: controller,
  linkSettings: LinkSettings(
    rules: [
      .regex(
        id: 'issue',
        pattern: RegExp(r'#(\d+)'),
      ),
    ],
    onActivate: (link) {
      if (link.id == 'issue') openIssue(link.text.substring(1));
    },
  ),
);

```

### Custom Terminal Theme Configuration

Source: https://pub.dev/packages/flterm

Create custom terminal themes by directly constructing a TerminalTheme object. This allows for detailed customization of the color palette, font family, font size, and cursor shape.

```dart
TerminalView(
  controller: controller,
  theme: TerminalTheme(
    palette: ColorPalette(
      ansiColors: const [/* 16 ANSI colors */],
      background: const Color(0xFF1D1F21),
      foreground: const Color(0xFFC5C8C6),
    ),
    fontFamily: 'JetBrains Mono',
    fontSize: 14,
    cursor: const CursorTheme(shape: CursorShape.bar),
  ),
);

```

--------------------------------

### Add flterm Dependency with Flutter

Source: https://pub.dev/packages/flterm/install

Run this command to add the flterm package as a dependency to your Flutter project. This command automatically updates your pubspec.yaml file.

```bash
$ flutter pub add flterm
```

--------------------------------

### Add flterm Dependency

Source: https://pub.dev/packages/flterm

Add the flterm package to your project's dependencies in pubspec.yaml.

```yaml
dependencies:
  flterm: ^0.0.4

```

--------------------------------

### Programmatic Terminal Control

Source: https://pub.dev/packages/flterm

Control the terminal programmatically using the TerminalController. This includes sending text, managing selection, clipboard operations, and clearing the terminal.

```dart
// I/O
controller.sendText('ls -la\n');

// Selection
controller.selectAll();
print(controller.selectedText());

// Clipboard
controller.paste('hello');

// Reset
controller.clear();

```
