Getting Started

Usage

To use the Button widget, import the package and place it within your widget tree:

import 'package:miv_buttons/button.dart';
import 'package:flutter/material.dart';

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Custom Button Example'),
      ),
      body: Center(
        child: Button(
          onClick: () {
            print('Button pressed');
          },
          child: Text('Click Me'),
          color: Colors.blue,
          borderRadius: 8.0,
          horizontalPadding: 16.0,
          verticalPadding: 12.0,
          elevation: 6.0,
          pressedElevation: 2.0,
        ),
      ),
    );
  }
}

Named Constructors

The miv_buttons package provides additional named constructors to create buttons with specific layouts more easily. These constructors help in quickly setting up common button types like icon buttons or buttons with labels. At the moment there are 4 options: Button.label(), Button.icon(),Button.iconLabel() and Button.labelIcon()

`Button.label()`

This constructor creates a button with a text label. It is useful when you need a simple text-based button.

Button.label(
  onClick: () {
    print('Label button pressed');
  },
  label: 'Submit',
  color: Colors.green,
  labelColor: Colors.black,
)

`Button.icon()`

This constructor is designed to create a button that features an icon. It is perfect for use cases where a simple visual button is required without text labels.

Button.icon(
  onClick: () {
    print('Icon button pressed');
  },
  icon: Icons.thumb_up,
  color: Colors.orange,
  iconColor: Colors.black,
)

`Button.iconLabel()`

This constructor is designed to create a button that includes both an icon and a text label. The icon is on the left of the label if isHorizontal is true (default). When you set isHorizontal to false, the icon will appear over the label.

Button.iconLabel(
  onClick: () {
    print('Button pressed');
  },
  icon: Icons.face,
  label: 'Log out',
  color: Colors.redAccent,
  foregroundColor: Colors.white,
  gap: 12.0,
)

`Button.labelIcon()`

Similarly to the previous one, this constructor is designed to create a button that includes both an icon and a text label. This time the label is on the left of the icon if isHorizontal is true (default). When you set isHorizontal to false, the label will appear over the icon.

Button.labelIcon(
  onClick: () {
    print('Button pressed');
  },
  icon: Icons.arrow_forward,
  label: 'Continue',
  color: Colors.indigo,
  foregroundColor: Colors.white,
)
