loading_kit 0.2.0

A blocking-async overlay that never flickers. Wrap any Future in one call: delayed reveal, minimum display time, reference counting, cancellation, and themed presets.

0.2.0

Everything is now a token. Nothing about the indicator, the card, or the toasts is hardcoded any more.

Added

• LoadingMotion controls animation speed: spinPeriod, morphDuration, progressDuration, barSweepPeriod, crossFadeDuration. Ships with standard, brisk and calm profiles.
• LoadingToastStyle controls toast chrome: padding, radius, icon size and stroke, gaps, enter duration.
• Card metrics as tokens: cardMinWidth, textGap, cancelMinimumSize, cancelPadding.
• LoadingProgressBar takes sweepPeriod and fillDuration directly.
• LoadingController takes toastExitDuration, defaultToastDuration and maxVisibleToasts.

Fixed

• A cardMinWidth above maxCardWidth produced non-normalized constraints and threw. The pair is now clamped, since both come from the caller.

Breaking

• LoadingController.toastExitDuration, defaultToastDuration and maxVisibleToasts moved from statics to instance fields set on the constructor. The duration argument to toast is now nullable and falls back to the controller's own default.

0.1.0

Initial release.

Indicators

• Six indeterminate forms — arc, dots, bars, orbit, pulse, ripple — all settling into the same check or cross.
• indicatorBuilder replaces the built-in indicator with any widget, so Lottie, Rive, or another spinner package can be dropped straight in.
• LoadingProgressStyle.bar draws determinate progress as a linear bar.

Beyond the full-screen overlay

• Loading.toast / toastSuccess / toastError for transient, non-blocking messages that never intercept input.

• LoadingBarrier scopes the overlay to a single subtree while still applying the timing policy.

• Loading.run / runTask wrap a future behind the overlay in one call.

• Timing policy with a reveal delay and a minimum-visible window, so fast operations paint nothing and slow ones do not blink out.

• Reference counting across concurrent operations, with a running operation outranking one that has already settled.

• Determinate progress, cooperative cancellation, and timeouts.

• Success and error states drawn as one continuous morph of the arc rather than a widget swap.

• Five presets — cupertino, material, glass, minimal, neon — plus adaptive, all resolving against the ambient theme in light and dark.

• Route awareness via LoadingNavigatorObserver.

• Input blocking, focus trapping, live-region announcements, BlockSemantics, and reduced-motion support.

• LoadingIndicator usable standalone, with no overlay or controller.
