Glutton

Flutter shared preferences customized plugin. Secure, Encrypted, Simplified use, Simple key-value pairs storage.

Getting Started

In your flutter project add the dependency:

dependencies:
  ...
  glutton: ^1.0.1

Usage

Importing package

import 'package:glutton/glutton.dart';

Using Glutton

Saving data inside glutton

bool isSuccess = await Glutton.eat(key, data);

Retrieve data inside glutton

dynamic data = await Glutton.vomit(key);

Check if data is exist inside glutton

bool isExist = await Glutton.have(key);

Remove data inside glutton

bool isSuccess = await Glutton.digest(key);

Clear all data inside glutton

await Glutton.flush();

Can we save class object?

The current answer is no.

Written in JSON and Serialization, flutter doesn't provide library like GSON or Moshi. Such a library would require using runtime reflection, which is disabled in Flutter. So we can't automatically turn class into json or the opposite.

Edible data type

• List
• Set
• Map (can eat json here)
• DateTime
• String
• bool
• int (can eat enum index here)
• double

Example

Save & retrieve class

Save:

/// 1. Create user object
User user = User(
  name: "Gentleton,,
  age: "21",
  createdAt: DateTime.now(),
);

/// 2. Transform user object to map
Map<String, dynamic> userMap = user.toJson();

/// 3. Save user map inside glutton
bool isSuccess = await Glutton.eat(<UserKey>, userMap);

Retrieve

/// 1. Retrieve user map inside glutton
Map<String, dynamic> userMap = await Glutton.vomit(<UserKey>);

/// 2. Transform user map to user object
User user = User.fromJson(userMap);

Save & retrieve date

Save:

/// 1. Set selected date
DateTime date = await showDatePicker(
  context: context,
  initialDate: _selectedDate,
  firstDate: DateTime(1990),
  lastDate: DateTime(2030),
);

/// 2. Save selected date inside glutton
await Glutton.eat(<DateKey>, date);

Retrieve

/// 1. Retrieve user map inside glutton
DateTime date = await Glutton.vomit(<DateKey>);

Save & retrieve enum

Save:

/// 1. Retrieve index of enum
int index = Season.index;

/// 2. Save index inside glutton
await Glutton.eat(<enumKey>, index);

Retrieve

/// 1. Retrieve index inside glutton
int index = await Glutton.vomit(<enumKey>);

/// 2. Transform index to enum
Season _season = SeasonManager.fromIndex(index); 

You can follow Season enum for step 2 retrieve enum
