How to Use the Flutter Debug Console

 ✅ What Is the Flutter Debug Console?

The Debug Console is part of your IDE (like Visual Studio Code or Android Studio) where:


Flutter print statements appear


Error and exception logs are shown


Stack traces and debug messages are printed


You can input commands in debug mode (like hot reload, hot restart)


🛠️ How to Use It in Different IDEs

🔹 1. In Visual Studio Code

📍Steps:

Open your Flutter project in VS Code.


Click on Run > Start Debugging or press F5.


The Debug Console tab will appear automatically.


Add print() statements in your Dart code:


dart

Copy

Edit

print('Button clicked!');

Output appears in the Debug Console.


🧠 Tips:

Use debugPrint() for long logs:


dart

Copy

Edit

debugPrint('This is a debug message');

🔹 2. In Android Studio / IntelliJ

📍Steps:

Open your project.


Click Run > Debug ‘main.dart’.


Look at the Run or Debug window at the bottom.


Logs, prints, and Flutter errors will show here.


🛠️ Useful Shortcuts:

Hot Reload: Ctrl + \ (Windows/Linux) or Cmd + \ (Mac)


Hot Restart: Click the restart button in the toolbar or use the appropriate shortcut.


🔹 3. Flutter CLI (Terminal)

You can also run your app via terminal:


bash

Copy

Edit

flutter run

You’ll see:


Console logs


print() output


Errors and stack traces


You can press:


r for hot reload


R for hot restart


q to quit


🧪 Common Console Commands in Debug Mode

Command Action

r Hot reload

R Hot restart

q Quit the app

p Toggle performance overlay


🧩 Best Practices

Use debugPrint() instead of print() for long text to avoid console truncation.


Wrap logs with tags:


dart

Copy

Edit

debugPrint('[LOGIN_SCREEN] Login button pressed');

Use Flutter DevTools for advanced debugging (memory, performance, etc.).


📌 Summary

Task Method

View logs and prints Use Debug Console

Debug errors Watch stack traces

Hot reload/restart Use IDE or terminal keys

Long logs Use debugPrint()

Advanced debugging Use Flutter DevTools

Handling Frames and Iframes Using Playwright

Handling Frames and Iframes Using Playwright When automating modern web applications, you’ll often come across frames or iframes—HTML elements used to embed another HTML document within the current page. If you're using Playwright for browser automation, knowing how to handle frames properly is crucial for interacting with elements inside them. In this blog, we’ll walk through how to identify, access, and interact with frames and iframes using Playwright with code examples in JavaScript and Python. 🧾 What Are Frames and Iframes? <frame>: Rarely used now; part of the outdated <frameset> HTML structure. <iframe> (inline frame): Embeds another HTML page inside the current one. Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...

Working with Tosca Parameters (Buffer, Dynamic Expressions)

🧪 Working with Tosca Parameters (Buffer, Dynamic Expressions) In Tricentis Tosca, parameters help you make your tests flexible, reusable, and data-driven. Two powerful types of parameters in Tosca are: Buffers Dynamic Expressions Let’s understand each one and how to use them effectively. 🟦 1. What is a Buffer in Tosca? A Buffer is a temporary in-memory storage used to store values during test execution. You can store a value in a buffer and then reuse it anywhere in your test case. 🔹 When to use: Save a value from one step and reuse it later Pass values between test steps or modules Dynamically build test data ✅ How to Create a Buffer In a Tosca TestStep, you use the syntax: text Copy Edit =>BufferName This saves a value to a buffer. Example: Capture an Order ID after placing an order: text Copy Edit ActionMode: Buffer Value: =>OrderID This stores the Order ID in a buffer named OrderID. ✅ How to Use a Buffer You can reuse the buffer value like this: text Copy Edit {B[OrderID]}...
