flutter pub add localstorage
1- Add dependency to pubspec.yaml (Change the version based on the last)

dependencies:
  ...
  localstorage: ^4.0.0+1
2- Then run the following command

flutter packages get
3- import the localstorage :

import 'package:localstorage/localstorage.dart';
4- create an instance

class MainApp extends StatelessWidget {
  final LocalStorage storage = new LocalStorage('localstorage_app');
  ...
}
Add item to lcoalstorage :

void addItemsToLocalStorage() {
  storage.setItem('name', 'Abolfazl');
  storage.setItem('family', 'Roshanzamir');

  final info = json.encode({'name': 'Darush', 'family': 'Roshanzami'});
  storage.setItem('info', info);
}
Get an item from lcoalstorage:

void getitemFromLocalStorage() {
  final name = storage.getItem('name'); // Abolfazl
  final family = storage.getItem('family'); // Roshanzamir
  
  Map<String, dynamic> info = json.decode(storage.getItem('info'));
  final info_name=info['name'];
  final info_family=info['family'];
}
Delete an item from localstorage :

void removeItemFromLocalStorage() {
  storage.deleteItem('name');
  storage.deleteItem('family');
  storage.deleteItem('info');
}

Simple solution, you can make the file structure more complex
Package: path_provider


import 'dart:convert';
import 'dart:io';

import 'package:path_provider/path_provider.dart';

abstract class OurDataStorage {
  static Future<String> get documentsDirectoryPath async {
    return (await getApplicationDocumentsDirectory()).path;
  }

  static Future<String> get temporaryDirectoryPath async {
    return (await getTemporaryDirectory()).path;
  }

  static Future writeDocument(String document, Map<String, dynamic> data) async {
    await File("${await documentsDirectoryPath}/$document.json").writeAsString(jsonEncode(data));
  }

  static Future writeTemporary(String document, Map<String, dynamic> data) async {
    await File("${await temporaryDirectoryPath}/$document.json").writeAsString(jsonEncode(data));
  }

  static Future<Map<String, dynamic>> readDocument(String document) async {
    return jsonDecode(await File("${await documentsDirectoryPath}/$document.json").readAsString());
  }

  static Future<Map<String, dynamic>> readTemporary(String document) async {
    return jsonDecode(await File("${await temporaryDirectoryPath}/$document.json").readAsString());
  }

  static Future updateDocument(String document, Map<String, dynamic> data) async {
    final fileData = await readDocument(document);
    data.forEach((key, value) => fileData[key] = value);
    await writeDocument(document, fileData);
  }

  static Future updateTemporary(String document, Map<String, dynamic> data) async {
    final fileData = await readTemporary(document);
    data.forEach((key, value) => fileData[key] = value);
    await writeTemporary(document, fileData);
  }

  static Future deleteDocument(String document) async {
    await File("${await documentsDirectoryPath}/$document.json").delete();
  }

  static Future deleteTemporary(String document) async {
    await File("${await temporaryDirectoryPath}/$document.json").delete();
  }

  static Future clearDocuments() async {
    final directory = await getApplicationDocumentsDirectory();
    await directory.delete(recursive: true);
    await directory.create();
  }

  static Future clearTemporary() async {
    final directory = await getTemporaryDirectory();
    await directory.delete(recursive: true);
    await directory.create();
  }
}
