# Flutter

### Dependências

Para criar uma WebView em uma aplicação Flutter, é necessário adicionar as dependências [flutter\_inappwebview](https://pub.dev/packages/flutter_inappwebview) e [permission\_handler](https://pub.dev/packages/permission_handler) ao seu `pubspec.yaml`:

```yaml
dependencies:
  flutter:
    sdk: flutter
  flutter_inappwebview: ^6.0.0
  permission_handler: ^11.3.1
```

### Manifesto do Android

Adicione estas linhas ao arquivo AndroidManifest.xml no módulo do seu app Android:

```xml
<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
```

### Info.plist do iOS

Adicione estas linhas ao arquivo Info.plist no seu módulo iOS:

```plist
<key>NSCameraUsageDescription</key>
<string>Permissão da câmera</string>
<key>NSMotionUsageDescription</key>
<string>Permissão de movimento</string>
```

### WebView do Flutter (Dart)

Este é um exemplo de uma activity usando uma WebView

```dart
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
import 'package:permission_handler/permission_handler.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Demonstração Flutter',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const WebViewScreen(),
    );
  }
}

class WebViewScreen extends StatefulWidget {
  const WebViewScreen({super.key});

  @override
  _WebViewScreenState createState() => _WebViewScreenState();
}

class _WebViewScreenState extends State<WebViewScreen> {
  InAppWebViewController? webViewController;

  @override
  void initState() {
    super.initState();
    _checkCameraPermission();
  }

  Future<void> _checkCameraPermission() async {
    var status = await Permission.camera.status;
    if (!status.isGranted) {
      await Permission.camera.request();
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Exemplo de WebView do Flutter')),
      body: InAppWebView(
        initialUrlRequest: URLRequest(
          url: WebUri.uri(Uri.parse('https://cadastro.io/:token')),
        ),
        onWebViewCreated: (controller) {
          webViewController = controller;
        },
        androidOnPermissionRequest: (controller, origin, resources) async {
          return PermissionRequestResponse(
            resources: resources,
            action: PermissionRequestResponseAction.GRANT,
          );
        },
      ),
    );
  }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.caf.io/caf-docs/caf-product-guides-pt-br/guias-de-inicio-rapido/onboardings-integration/webview/webview_flutter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
