flutter - How to change ElevatedButton size

Flutter - ElevatedButton Size
The ElevatedButton class represents a material design elevated button. The flutter developers can use elevated buttons to add dimension to otherwise mostly flat layouts such as in long busy lists of content, or in wide spaces. The flutter developers should avoid using elevated buttons on already-elevated content such as dialogs or cards. The flutter developers can override the ElevatedButton style with its style parameter. The static styleFrom() method is a convenient way to create an ElevatedButton ButtonStyle from simple values.

The following flutter application development tutorial will demonstrate how we can set the size of an ElevatedButton widget. Here we will use the ElevatedButton class’s styleFrom() method to change the ElevatedButton widget’s size (both width and height).

The ElevatedButton class’s styleFrom() method is a static convenience method that constructs an elevated button ButtonStyle given simple values. By default, ElevatedButton class styleFrom() method returns a ButtonStyle that doesn't override anything.

The ButtonStyle class represents the visual properties that most buttons have in common. The ButtonStyle class’s all properties are null by default.

The flutter developers can change an ElevatedButton’s width and height (size) by passing a value to the styleFrom() method’s fixedSize parameter.

The styleFrom() method’s fixedSize parameter value is a Size instance, which holds a 2D floating-point size. Here we used the Size class Size(double width, double height) constructors to create a Size with the given width and height.

So the flutter developers can pass their specified width and height value to this Size(double width, double height) constructor to set the specified size of an ElevatedButton widget.

So finally, the flutter app developers can change the ElevatedButton widget’s size (width and height) by passing a value (Size instance) to the ElevatedButton class’s styleFrom() method fixedSize parameter.
main.dart

import 'package:flutter/material.dart';

void main(){
  runApp(
      MaterialApp(
        home: Scaffold(
          appBar: AppBar(
              title: const Text("Flutter - ElevatedButton Size")
          ),
          body: Center(
              child: ElevatedButton(
                onPressed: (){},
                child: const Text("Click Me"),
                style: ElevatedButton.styleFrom(
                    primary: Colors.blueGrey,
                    fixedSize: const Size(200,75)
                ),
              )
          ),
        ),
      )
  );
}

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...
