How to show snakbar in fragment android koltin

In Android, a Snackbar is a component used to display lightweight notifications or messages to the user. It is often used to show quick feedback about an action or to display simple messages. To show a Snackbar in a fragment using Kotlin, follow these steps:

Import the necessary dependencies:

Make sure you have the appropriate dependencies added to your build.gradle file:

gradle
implementation 'com.google.android.material:material:1.4.0' // Make sure to use the latest version

Create and show the Snackbar in your fragment:

In your Fragment's Kotlin code, you can use the Snackbar.make() method to create and display a Snackbar. Here's an example:

kotlin
import android.os.Bundle
import androidx.fragment.app.Fragment
import android.view.LayoutInflater 
import android.view.View
import android.view.ViewGroup 
import com.google.android.material.snackbar.Snackbar 
class MyFragment : Fragment() {
private lateinit var rootView: View
// The root view of your fragment layout 
override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
 rootView = inflater.inflate(R.layout.fragment_my, container, false)
return rootView 
 } 
fun showSnackbar(message: String)
 { 
 Snackbar.make(rootView, message, Snackbar.LENGTH_SHORT).show()
    } 
}

Call the showSnackbar() method from your fragment: You can call the showSnackbar() method from your fragment whenever you want to display a Snackbar. For example, you can call it in response to a button click or any other event:

kotlin
class MyFragment : Fragment() { 

fun onSomeButtonClicked() { 
 showSnackbar("Button clicked!")
 } 
}

Uncaught Error: Call to undefined function curl_init()

Method 1

Enable cURL:

If cURL is not enabled, you'll need to enable it. Depending on your hosting environment, you might have access to modify the PHP configuration file (php.ini) or use a control panel to enable the cURL extension.
a. If you have access to the php.ini file, find and uncomment the line containing extension=curl, removing the semicolon (;) at the beginning of the line if present. After making this change, save the file and restart your web server.
b. If you don't have direct access to the php.ini file, check if your hosting provider or server administrator offers a control panel (e.g., cPanel, Plesk, etc.) where you can enable the cURL extension.

Method 2

In Ubuntu, you can install the cURL package using the package manager called apt. Here's the step-by-step guide to install cURL on Ubuntu:
