Flutter Path Provider

Flutter Path Provider:

The Flutter plugin used for finding commonly used locations on the filesystem of the device. It Supports for both  iOS and Android.

Sample  Example code:

Directory tempDir = await getTemporaryDirectory();
String tempPath = tempDir.path;

Directory appDocDir = await getApplicationDocumentsDirectory();
String appDocPath = appDocDir.path;

 

Using Path Provider In Flutter:

Adding the dependency package into the Flutter:

Use the below code to add the dependency package into the  pubspec.yaml file:

dependencies:

path_provider: ^0.4.1

Installing the dependency package into the Flutter:

Use the below code to install dependency package into the Flutter from Terminal Editor Command

 $ flutter packages get

By default Flutter  supports flutter packages get.

 Importing the dependency package into the Flutter Dart Code:

Use the below code to import the dependency package into the flutter. Without importing if we use it

it will shows package not found exception.

import 'package:path_provider/path_provider.dart';

 

Below is the Example of Flutter Path Provider for  both Android and IOS:

Create Flutter project copy and paste below code into example/lib/main.dart file:

 

import 'dart:async';
import 'dart:io';

import 'package:flutter/material.dart';
import 'package:path_provider/path_provider.dart';

void main() {
runApp(new MyApp());
}

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Path Provider',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(title: 'Path Provider'),
);
}
}

class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;

@override
_MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
Future<Directory> _tempDirectory;
Future<Directory> _appDocumentsDirectory;
Future<Directory> _externalDocumentsDirectory;

void _requestTempDirectory() {
setState(() {
_tempDirectory = getTemporaryDirectory();
});
}

Widget _buildDirectory(
BuildContext context, AsyncSnapshot<Directory> snapshot) {
Text text = const Text('');
if (snapshot.connectionState == ConnectionState.done) {
if (snapshot.hasError) {
text = new Text('Error: ${snapshot.error}');
} else if (snapshot.hasData) {
text = new Text('path: ${snapshot.data.path}');
} else {
text = const Text('path unavailable');
}
}

return new Padding(padding: const EdgeInsets.all(16.0), child: text);
}

void _requestAppDocumentsDirectory() {
setState(() {
_appDocumentsDirectory = getApplicationDocumentsDirectory();
});
}

void _requestExternalStorageDirectory() {
setState(() {
_externalDocumentsDirectory = getExternalStorageDirectory();
});
}

@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text(widget.title),
),

body: new Center(
child: new Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
new Column(
children: <Widget>[
new Padding(
padding: const EdgeInsets.all(16.0),
child: new RaisedButton(
child: const Text('Get Temporary Directory'),
onPressed: _requestTempDirectory,
),
),
],
),

new Expanded(
child: new FutureBuilder<Directory>(
future: _tempDirectory, builder: _buildDirectory),
),

new Column(
children: <Widget>[
new Padding(
padding: const EdgeInsets.all(16.0),
child: new RaisedButton(
child: const Text('Get Application Documents Directory'),
onPressed: _requestAppDocumentsDirectory,
),
),
],
),

new Expanded(
child: new FutureBuilder<Directory>(
future: _appDocumentsDirectory, builder: _buildDirectory),
),

new Column(children: <Widget>[
new Padding(
padding: const EdgeInsets.all(16.0),
child: new RaisedButton(
child: new Text('${Platform.isIOS ?
"External directories are unavailable "
"on iOS":
"Get External Storage Directory" }'),
onPressed:
Platform.isIOS ? null : _requestExternalStorageDirectory,
),
),
]),

new Expanded(
child: new FutureBuilder<Directory>(
future: _externalDocumentsDirectory,
builder: _buildDirectory),
),
