Breaking It Down

Let's go through the steps to ensure you're not making similar mistakes in the future:

Check for Typos: Ensure that you are using modifier and not Modifer. It's a common typo that can easily slip by unnoticed.

Understanding the Modifier: In Jetpack Compose, the modifier parameter is essential for customizing the behavior and appearance of composables. This can include scrollable behavior, padding, alignment, and more.

Using Horizontal Scroll: The Modifier.horizontalScroll(scroll) enables horizontal scrolling for your text content—a fantastic feature for managing longer strings that shouldn’t overflow their container.

Conclusion

Never underestimate the impact of small typos in programming! A simple misspelling can lead to frustrating errors that stall your workflow. With the correct usage of modifier, you can easily enhance your Text composables in Jetpack Compose.

Now that you’re aware of the proper syntax, go ahead and make those modifications without any worries. Happy coding!
