material_async_button 2.0.2

Drop-in async wrappers for Flutter Material buttons. Adds a loading state, with theming via ThemeExtension and external control via a controller.

CHANGELOG

2.0.2

Fixed

• Buttons no longer shrink by a sub-pixel while loading. The default spinner now sizes to the label's line-box height (the idle content's vertical extent) rather than the raw fontSize, which is shorter than the rendered line. .icon buttons take max(iconSize, lineBox), text-only buttons take the line box, icon-only buttons keep iconSize (unchanged). The line box is measured with the ambient TextScaler, so the loading view also tracks text scaling.

2.0.1

Fixed

• Icon-bearing buttons no longer shrink vertically while loading. The default spinner sizes to the button's shape instead of always to the font size: iconSize for IconAsyncButton, max(iconSize, fontSize) for the .icon constructors (the idle row height), and fontSize for text-only buttons (unchanged). Sizes are read from the button's resolved IconTheme / DefaultTextStyle, so a per-widget iconSize and theme overrides flow through.

2.0.0

Breaking redesign. The button now does exactly one job — show a spinner while onPressed is in flight — and stays out of error handling, success feedback, and styling. State collapses to a single bool (loading), and the theme becomes a pure complement to ButtonStyle.

Breaking

• Loading-only: no success or error state. Removed AsyncButtonStatus entirely (the state is now a plain bool isLoading), along with onSuccess, onError, successBuilder, errorBuilder, feedbackDuration, cooldownDuration, markSuccess, markError, haptic / HapticOn, and announce / AsyncButtonAnnouncer / defaultAsyncButtonAnnouncer. An in-button error view is a Material anti-pattern; success is handled by what your action already does (navigate away, flip the label). Both belong to your state management, not the button.
• onPressed throws now re-propagate. When onPressed throws, the button returns to idle and re-throws so the error reaches FlutterError.onError / your runZonedGuarded zone. controller.trigger() rethrows instead of completing normally.
• AsyncButtonController is now a read-only ValueListenable<bool> (ChangeNotifier implements ValueListenable<bool>). There is no public value setter — drive it with trigger() / reset() and observe with addListener / ValueListenableBuilder<bool>. Builders receive bool isLoading instead of an AsyncButtonStatus.
• AsyncButtonTheme carries only loadingBuilder + transitionBuilder. AsyncButtonTheme.empty (spinner-only) is the sole baseline; removed AsyncButtonTheme.material(). It complements ButtonStyle — no styling.
• disabled flag → enabled (defaults to true). Affirmative naming that pairs with a tear-off onPressed. Either enabled: false or onPressed: null disables — both also no-op an external controller.trigger().
• loadingChild (a Widget) → loadingBuilder (a WidgetBuilder) on both the widgets and AsyncButtonTheme.
• Removed the loading-colour knobs (loadingForegroundColor, material(loadingColor:)). The spinner inherits each button variant's foreground; recolour a single button via AsyncButtonSpinner(color: ...).

Fixed

• Loading never disables the button. It keeps the button's themed enabled colours — being loading and being disabled are different things. The spinner inherits the enabled foreground for free (no more greyed indicator); taps that can't run are silently swallowed, and onLongPress is gated off while busy. The button shows the disabled look only when explicitly disabled via onPressed: null.
• .icon buttons drop the icon while loading, rendering the spinner alone.

Improved

• The default AsyncButtonSpinner derives its size from the ambient font size, so it matches the button's label instead of a fixed 16px.
• Guarded against state changes on an unmounted button.
• Corrected the flutter SDK constraint.

1.0.1

• Docs: use tear-off form (onPressed: api.save) in README examples.
• CI: split workflow into format/analyze/test/pana/example, add tag-triggered pub.dev publish via OIDC trusted publishing.

1.0.0

Initial release. Renamed from async_button_builder to material_async_button with a redesigned, theme-aware API.
