Material & Cupertino SpinBox for Flutter

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).
