Hi and welcome to this tutorial.
Today we're going to dive into the exciting topic of event handling.
Event handling is an essential concept
in any type of programming, and React Native is no exception.
It allows us to create interactive and dynamic applications by responding
to user input and other events that happen within our app.
Now let's dive into the code and see how event handling works.
You're now looking at my screen
with my edit opened exactly where we left off in the last lesson.
I have the simulator running and I have the Metro bundler running here as well.
For example, let's go back to my text
component that we created a couple of lessons ago.
And let's set up an alert when.
The text is clicked.
First of all, what we need to do is use the Mytext component here.
So let's change the item here and.
Let'S import Mytext component instead.
And then let's use the Mytext component here.
Great. We now see our text as we saw before.
Now let's go to Mytext component.
And here let's set up an event that will show us an alert when text is clicked.
This is made possible by handling the.
Onpress event of the text component.
And we're going to be attaching the.
Function to this event and we're going to specify what should happen when the.
User clicks the text.
So let's say a function should execute here called Handle Text click.
And let's set up this function here.
And let's make it show us an alert that the text has been clicked.
Let's save this and then let's just.
Go here and click on our text component.
And once we click, we see an alert and it says the text has been clicked.
Event handling is important because it
allows us to create interactive and responsive application,
and it a fundamental building block in React Native development.
With the help of event handling, we can create variety of interactions
including button clicks, text input, swipe gestures, and much more.
So now you know the basics of event handling in React Native.
Give it a try and start creating dynamic and interactive applications today.
Thanks for watching. See you in the next video.
