ThresholdSliderRow class

One labeled slider row — the prefix (0.25 Confidence Threshold) shows the live value with the label baked in.

Styling mirrors yolo-ios-app/Sources/YOLO/YOLOView.swift#setupUI:

  • labelSliderConf.font = UIFont.preferredFont(forTextStyle: .subheadline) (lines 577/586) — subheadline in iOS is ~15pt regular, so we use bodyMedium/15 with FontWeight.w400.
  • slider.minimumTrackTintColor = .white (line 630).
  • slider.maximumTrackTintColor = .systemGray.withAlphaComponent(0.7) (line 631). CupertinoSlider is used over Material's Slider because the iOS-style thin track with a circular thumb is what the showcase reference uses; SliderTheme can't reshape Material's wider track to match without re-painting.

Properties

divisions → int?
Discrete divisions, or null for a continuous slider.
final
hashCode → int
The hash code for this object.
no setterinherited
isInt → bool
When true the value is rendered with no decimal places (numItems).
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
label → String
Slider label suffix (e.g. Confidence Threshold).
final
max → double
Slider maximum.
final
min → double
Slider minimum.
final
onChanged → ValueChanged<double>
Invoked on every drag tick.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sliderWidthFactor → double
Fraction of the available width the slider track occupies (iOS sliderWidth = width * 0.46). The caption above always spans full width so it never wraps.
final
