flutter - How to add shadow to the Text

Flutter - Add shadow to the Text
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 add shadow to the Text. We will draw a shadow for the text. Here we will assign a TextStyle instance for the Text widget’s style property.

Then we will use the TextStyle class’s shadows property to add a shadow to the Text. We will also set the shadow color, offset and blur using the Shadow class’s various properties.

The Text class’s style property value is a TextStyle object. The TextStyle class represents an immutable style describing how to format and paint text.

The TextStyle class’s shadows property value is a list of Shadows that will be painted underneath the text. Multiple shadows are supported to replicate lighting from multiple light sources.

The Shadow class represents a single shadow. Multiple shadows are stacked together in a TextStyle. The Shadow class’s color property value is the color with which the shadow will be drawn.

The Shadow class’s offset property value is an Offset which is the displacement of the shadow from the casting element. The Positive x and y offsets will shift the shadow to the right and down and the negative offsets shift the shadow to the left and up. The Offset class represents an immutable 2D floating-point offset.

The Shadow class’s blurRadius property value is a Double instance which is the standard deviation of the Gaussian to convolve with the shadow's shape.

So finally, the flutter app developers can add a shadow to the text using the TextStyle class shadows property. They also have to set the various properties value for the Shadow object to customize the shadow appearance.
main.dart

import 'package:flutter/material.dart';

        home: Scaffold(
          appBar: AppBar(
              title: const Text("Flutter - Text Shadow")
          ),
          body: const Center(
            child: Text(
              "Lorem Ipsum is simply dummy text of the printing"
                  " and typesetting industry.",
              style: TextStyle(
                shadows: [
                  Shadow(
                      color: Colors.grey,
                      offset: Offset(2, 3),
                      blurRadius: 3
                  )
                ],
                fontSize: 25,
              ),
              textAlign: TextAlign.center,
            ),
          ),
        ),
      )
  );

Restricting Jetpack Compose TextField to Numeric Input Only

Jetpack Compose has revolutionized Android development with its declarative approach, enabling developers to build modern, responsive UIs more efficiently. Among the many components provided by Compose, TextField is a critical building block for user input. However, ensuring that a TextField accepts only numeric input can pose challenges, especially when considering edge cases like empty fields, invalid characters, or localization nuances. In this blog post, we'll explore how to restrict a Jetpack Compose TextField to numeric input only, discussing both basic and advanced implementations. Why Restricting Input Matters Restricting user input to numeric values is a common requirement in apps dealing with forms, payment entries, age verifications, or any data where only numbers are valid. Properly validating input at the UI level enhances user experience, reduces backend validation overhead, and minimizes errors during data processing. Compose provides the flexibility to implement ...

jetpack compose - TextField remove underline

Compose TextField Remove Underline The TextField is the text input widget of android jetpack compose library. TextField is an equivalent widget of the android view system’s EditText widget. TextField is used to enter and modify text. The following jetpack compose tutorial will demonstrate to us how we can remove (actually hide) the underline from a TextField widget in an android application. We have to apply a simple trick to remove (hide) the underline from the TextField. The TextField constructor’s ‘colors’ argument allows us to set or change colors for TextField’s various components such as text color, cursor color, label color, error color, background color, focused and unfocused indicator color, etc. Jetpack developers can pass a TextFieldDefaults.textFieldColors() function with arguments value for the TextField ‘colors’ argument. There are many arguments for this ‘TextFieldDefaults.textFieldColors()’function such as textColor, disabledTextColor, backgroundColor, cursorC...

jetpack compose - Image clickable

Compose Image Clickable The Image widget allows android developers to display an image object to the app user interface using the jetpack compose library. Android app developers can show image objects to the Image widget from various sources such as painter resources, vector resources, bitmap, etc. Image is a very essential component of the jetpack compose library. Android app developers can change many properties of an Image widget by its modifiers such as size, shape, etc. We also can specify the Image object scaling algorithm, content description, etc. But how can we set a click event to an Image widget in a jetpack compose application? There is no built-in property/parameter/argument to set up an onClick event directly to the Image widget. This android application development tutorial will demonstrate to us how we can add a click event to the Image widget and make it clickable. Click event of a widget allow app users to execute a task such as showing a toast message by cli...
