SpinBox for Flutter

SpinBox for Flutter is a numeric input widget with an input field for entering a specific value, and spin buttons for quick, convenient, and accurate value adjustments.

Guidelines

Spin boxes are best suited for such applications

• that deal with large numeric value ranges and high precisions,
• where users typically know upfront the exact value they are entering,
• where users may later have a need to accurately adjust a previously entered value.

As a rule of thumb, spin boxes are great for scenarios where

• sliders and alike UI controls are too inaccurate,
• tumblers and alike UI controls cannot provide enough value range,
• and a plain text field is inconvenient for value adjustments (open the VKB, move the cursor, erase the previous value, enter a new value... vs. tap-tap-done).

Designs

SpinBox for Flutter comes in two variants. It provides implementations for both designs in Flutter, Material and Cupertino (iOS).

Material Design

import 'package:flutter_spinbox/material.dart'; // or flutter_spinbox.dart for both

SpinBox(
  min: 1,
  max: 100,
  value: 50,
  onChanged: (value) => print(value),
)

See also Material Components widgets package.

Cupertino (iOS-style) Design

import 'package:flutter_spinbox/cupertino.dart'; // or flutter_spinbox.dart for both

CupertinoSpinBox(
  min: 1,
  max: 100,
  value: 50,
  onChanged: (value) => print(value),
)

See also Cupertino (iOS-style) widgets package.
