Floating bottom navbar with MAUI .NET

Summary

The problem at hand is implementing a floating bottom navbar in a MAUI .NET application. The provided code snippet is for the HomePage.xaml file, which includes the design for the navbar but lacks functionality for navigation between pages. The goal is to make this navbar functional.

Root Cause

The root cause of the issue is the lack of implementation of navigation functionality in the provided XAML code. The code only defines the UI elements for the navbar but does not include any event handlers or commands to navigate between pages.

Why This Happens in Real Systems

This happens in real systems due to several reasons, including:

  • Lack of understanding of navigation patterns in MAUI .NET
  • Insufficient knowledge of XAML and its event handling mechanisms
  • Overlooking the importance of command binding for navigation

Real-World Impact

The real-world impact of this issue includes:

  • Poor user experience due to non-functional navigation
  • Increased development time to fix and implement navigation correctly
  • Potential for bugs and errors if navigation is not properly handled

Example or Code

// Example of navigating to a new page when a navbar item is clicked
private async void NavigateToPage(object sender, EventArgs e)
{
    await Navigation.PushAsync(new TargetPage());
}

How Senior Engineers Fix It

Senior engineers fix this issue by:

  • Implementing event handlers for each navbar item
  • Using command binding to navigate to different pages
  • Ensuring proper navigation pattern is followed to avoid complexity and bugs
  • Utilizing MVVM architecture to separate concerns and make the code more maintainable

Why Juniors Miss It

Juniors may miss this because they:

  • Lack experience with MAUI .NET and its navigation mechanisms
  • Are not familiar with XAML and its event handling capabilities
  • Overlook the importance of command binding and navigation patterns
  • Do not follow best practices for coding and architecture, leading to maintainability issues and bugs
