# MauiSettings
A nuget to improve settings storage (locally and eventually in the cloud) on .NET MAUI projects.The plugin idea is based on the Advexp.Settings.Local nuget by Alexey Ivakin
Repo: https://bitbucket.org/advexp/component-advexp.settings/src/master/
License: Apache-2.0 (https://licenses.nuget.org/Apache-2.0)This project was created from scratch, however uses the basic idea to keep all Settings in the
static object. All taken and changed files have been marked so.# Support me

## Settings Object
In the .NET MAUI project, create a new `Class` (for instance `SettingsApp.cs`) holding your setting properties.```cs
public partial class SettingsApp : MauiSettings
{
#region Settings#region Version
[MauiSetting(Name = nameof(App_SettingsVersion))]
public static Version App_SettingsVersion { get; set; } = new("1.0.0");#endregion
#region CloudSync
[MauiSetting(Name = nameof(Cloud_ShowInitialPrompt), DefaultValue = true)]
public static bool Cloud_ShowInitialPrompt { get; set; }[MauiSetting(Name = nameof(Cloud_ShowInitialPrompt), DefaultValue = SettingsStaticDefault.Cloud_EnableSync)]
public static bool Cloud_EnableSync { get; set; }
#endregion#region Theme
[MauiSetting(Name = nameof(Theme_UseDeviceDefaultSettings), DefaultValue = SettingsStaticDefault.General_UseDeviceSettings)]
public static bool Theme_UseDeviceDefaultSettings { get; set; }[MauiSetting(Name = nameof(Theme_UseDarkTheme), DefaultValue = SettingsStaticDefault.General_UseDarkTheme)]
public static bool Theme_UseDarkTheme { get; set; }[MauiSetting(Name = nameof(Theme_PrimaryThemeColor), DefaultValue = SettingsStaticDefault.Theme_PrimaryThemeColor)]
public static string Theme_PrimaryThemeColor { get; set; }#endregion
#region Localization
[MauiSetting(Name = nameof(Localization_CultureCode), DefaultValue = SettingsStaticDefault.Localization_Default)]
public static string Localization_CultureCode { get; set; }#endregion
#region Secure
// Encrypt: The value is encrypt before saving it on the device, and decrypt when loaded
// Note: Only `Secure` properties can be encrypted
[MauiSetting(Name = nameof(Localization_CultureCode), DefaultValue ="", Secure = true, Encrypt = true)]
public static string User_Username { get; set; }// SkipForExport: Value is not added to the Dictionary when exporting the settings
[MauiSetting(Name = nameof(Localization_CultureCode), DefaultValue ="", Secure = true, Encrypt = true, SkipForExport = true)]
public static string User_Password { get; set; }#endregion
#endregion
}
```## Load
To load the settings from the storage, call `SettingsApp.LoadSettings()` (mostly in the `App` constructor of your App.xmls file. The project uses the `Maui.Storage.Preferences` in order to store the settings on the corresponding device.## Save
Whenever you do make changes to a settings property of your class, call `SettingsApp.SaveSettings()`. This will write the settings to the storage.# Encryption
Starting from version `1.0.6`, you can encrypt secure properties with a `AES`encryption. An example how it works is shown below.
Sample: https://github.com/AndreasReitberger/MauiSettings/tree/main/src/MauiSettings.Example## App.xaml.cs
An example of how to load the settings from the `App.xaml`.```cs
public partial class App : Application
{
// Example key, it is recommended to generate the key on the device and save it as `Secure` property instead of
// adding it in clear text to the source code.
public static string Hash = "mYGUbR61NUNjIvdEv/veySPxQEWcCRUZ3SZ7TT72IuI=";
public App()
{
InitializeComponent();// Example of how to generate a new key
//string t = EncryptionManager.GenerateBase64Key();// Only Async methods do support encryption!
_ = Task.Run(async () => await SettingsApp.LoadSettingsAsync(Hash));
MainPage = new AppShell();
}protected override void OnSleep()
{
base.OnSleep();
if (SettingsApp.SettingsChanged)
{
try
{
SettingsApp.SaveSettings(Hash);
}
catch (Exception)
{}
}
}
}
```## MainPageViewModel
An example of a`ViewModel` loading and saving encrypted settings.
```cs
public partial class MainPageViewModel : ObservableObject
{
#region Settings
[ObservableProperty]
bool isLoading = false;[ObservableProperty]
string hashKey = App.Hash;[ObservableProperty]
string licenseInfo = string.Empty;
partial void OnLicenseInfoChanged(string value)
{
if (!IsLoading)
{
SettingsApp.LicenseInfo = value;
SettingsApp.SettingsChanged = true;
}
}[ObservableProperty]
ObservableCollection settings = [];
#endregion#region Ctor
public MainPageViewModel()
{
LoadSettings();
}
#endregion#region Methods
void LoadSettings()
{
IsLoading = true;LicenseInfo = SettingsApp.LicenseInfo;
IsLoading = false;
}
#endregion#region Commands
[RelayCommand]
async Task SaveSettings() => await SettingsApp.SaveSettingsAsync(key: App.Hash);[RelayCommand]
async Task LoadSettingsFromDevice()
{
try
{
await SettingsApp.LoadSettingsAsync(key: App.Hash);
LoadSettings();
}
catch(Exception)
{
// Throus if the key missmatches
}
}[RelayCommand]
async Task ExchangeHashKey()
{
string newKey = EncryptionManager.GenerateBase64Key();
await SettingsApp.ExhangeKeyAsync(oldKey: App.Hash, newKey: newKey);
App.Hash = HashKey = newKey;
LoadSettings();
}[RelayCommand]
async Task ToDictionary()
{
// All "SkipForExport" should be missing here.
Dictionary> dict = await SettingsApp.ToDictionaryAsync();
Settings = [.. dict.Select(kp => new SettingsItem() { Key = kp.Key, Value = kp.Value.Item1.ToString() })];
}
#endregion
}
