Flutter - Set Text word spacing The Text widget displays a string of text with a single style in a flutter app. But depending on the layout constraints the string might break across multiple lines or might all be displayed on the same line. The style argument is optional in a Text instance. When the style argument is omitted, the text will use the style from the closest enclosing DefaultTextStyle. By default, the Text is not selectable. But flutter developers can make a Text selectable by wrapping a subtree with a SelectionArea widget. The following flutter application development tutorial will demonstrate how we can set or change the Text word spacing. In this example code, we will increase the text word spacing instead of the default text word spacing. That means we will increase the gap between the Text widget’s text’s each word. In this flutter application, we will assign a TextStyle instance for the Text widget’s style property. Then we will use the...

Make Text Clickable In Compose The Text widget is a very important widget of the android jetpack compose library. The Text widget allows us to display text objects inside its surface. Commonly Text widget displays simple text on it. But an android jetpack compose developer can style this text using the Text widget’s ‘style’ argument. This ‘style’ argument allows us to define text decoration, font family, font weight, text color, etc. Android jetpack compose developer also can directly set The Text widget’s font family, font size, text color, text alignment, text letter spacing, etc using its parameters. But how can they set a click event for the Text widget when it has no default click event handler or onClick argument? The following code snippet will describe to us how we can set a click event handler for a Text widget. The Text widget modifier object has an element name ‘clickable’. This ‘clickable()’ method allows us to set an onClick event to a Text widget. Modifier’s click...

Understanding ClickableText in Jetpack Compose In the world of modern Android app development, Jetpack Compose stands out as a declarative UI toolkit that simplifies how we build dynamic and responsive user interfaces. Among its powerful components, ClickableText offers an intuitive way to handle text interactions without the need for traditional TextView or OnClickListener methods. This example demonstrates how ClickableText can be used to respond to user clicks on specific parts of the text, showcasing its flexibility and ease of use. The code we're exploring is a concise yet powerful implementation of ClickableText using Kotlin. This example not only illustrates how to create text elements that respond to user interactions but also demonstrates how to customize the text's appearance using styles like color, font size, and background. By the end of this walkthrough, you'll gain a solid understanding of how ClickableText works in Jetpack Compose and how to incorpora...

Introduction Jetpack Compose is Google's modern toolkit for building native Android user interfaces with less boilerplate and more intuitive design elements. For Android developers transitioning from the traditional XML-based UI approach, Jetpack Compose offers a fresh perspective with its declarative paradigm. In Jetpack Compose, instead of defining UI elements in XML files, you use Kotlin functions annotated with @Composable to construct the layout directly in code. This approach makes creating dynamic and responsive UIs faster and more efficient. In this article, we will break down a practical example that demonstrates how to use the Text composable in Jetpack Compose. The example includes several customization options for the Text element, such as color, font style, alignment, background color, and padding. Understanding how to manipulate these properties will allow developers to take full advantage of Jetpack Compose's flexibility when displaying text in their apps. Ov...
