Plugin.Maui.DynamicForms

A powerful .NET MAUI library for building dynamic, metadata-driven forms at runtime - no UI code required!

Build complex, production-ready forms in minutes with full validation, theming, and cross-platform support. Perfect for admin panels, data entry apps, configuration UIs, and any scenario requiring flexible form generation.

🎯 Why Plugin.Maui.DynamicForms?

Stop writing repetitive UI code. Define your forms once as metadata, and let the library handle the rest - rendering, validation, data binding, and styling.

1. Install via NuGet

dotnet add package Plugin.Maui.DynamicForms

2. Configure MauiProgram.cs

using CommunityToolkit.Maui;

builder.UseMauiApp<App>()
    .UseMauiCommunityToolkit();  // Required

3. Add Default Styles to App.xaml

<Application xmlns:styles="clr-namespace:Plugin.Maui.DynamicForms.Resources.Styles;assembly=Plugin.Maui.DynamicForms"
             ...>
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <styles:FormStyleDefault />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

4. Use in Your Page

<ContentPage xmlns:forms="clr-namespace:Plugin.Maui.DynamicForms.Controls;assembly=Plugin.Maui.DynamicForms"
             ...>
    <forms:DynamicFormView x:Name="MyFormView" />
</ContentPage>

// Define form structure
var fields = new FormBuilder()
    .BeginBlock("Contact Information")
        .AddTextField("Name").WithRequiredValidation()
        .AddTextField("Email").WithRequiredValidation()
        .AddTextField("Phone")
    .Build();

// Assign to form
MyFormView.FormFields = fields;

// Add Validators
MyFormView.FieldValidators.Add(new RequiredFieldValidator());

// Handle save
MyFormView.FormSaved += (s, e) => {
    var name = e.FormFields.First(f => f.Property == "Name").Value;
    // Process form data...
};

That's it! You now have a fully functional, validated, styled form. 🎉

🔥 Advanced Features

FluentValidation Integration

public class PersonValidator : AbstractValidator<PersonModel>
{
    public PersonValidator()
    {
        RuleFor(x => x.Email).EmailAddress();
        RuleFor(x => x.Age).InclusiveBetween(18, 100);
    }
}

MyForm.FormValidator = new FluentValidationFormValidator<PersonModel>(new PersonValidator());

Async API Data Loading

var customerData = await apiService.GetCustomerAsync(customerId);
var formFields = FormBuilder.CreateCustomerForm();
formFields = FormDataConverter.Dto2FormData(formFields, customerData);
MyForm.FormFields = formFields;

Multi-Block Forms

var form = new FormBuilder()
 .BeginBlock("Personal Info", isExpanded: true)
        .AddTextField("FirstName")
