How to pick a file in flutter web write full code and explain?
In Flutter web, you can use the file_picker package to pick a file from the user's device. Here is an example of how to use the package to pick a file and display its name:
import 'package:file_picker/file_picker.dart';
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _fileName;
void _pickFile() async {
File file = await FilePicker.getFile();
setState(() {
_fileName = file.path.split('/').last;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('File Picker Example'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(_fileName ?? 'No file selected'),
FlatButton(
onPressed: _pickFile,
child: Text('Pick File'),
),
],
),
),
);
}
}
- In this example, the _pickFile function is called when the user taps the "Pick File" button. This function uses the FilePicker.getFile() method to open the file picker and allow the user to select a file. Once a file is selected, the setState method is called to update the _fileName variable with the name of the selected file. The Text widget is used to display the file name on the screen.
- This code is an example of how to use the file_picker package to pick a file in Flutter web. It's important to note that the package support both single and multiple file selection, you can use FilePicker.getFiles() for multiple files selection.
- Additionally, the package support multiple file types, you can use FilePicker.getFile(type: FileType.image) for image file selection or FilePicker.getFile(type: FileType.audio) for audio file selection.
