Classes

M3EButton

M3EButton.

M3EButtonConstants

Shared numeric constants used throughout the button package.

M3EButtonDecoration

Styling overrides for M3EButton.

M3EButtonMeasurements

Resolved layout measurements for a button size variant.

M3EButtonTheme

Theme values for M3EButton.

M3EGradientOutlinePainter

Stroke painter for a rounded-rect outline (solid or gradient).

M3EToggleButtonDecoration

Styling overrides for M3EToggleButton and M3EButtonGroup.

Constants

m3eGradientForegroundSourceColor → const Color

Opaque white so BlendMode.srcIn shows the gradient as the content color.

Functions

m3eGradientBackgroundBuilder({required BorderRadius clipRadius, WidgetStateProperty<Gradient?>? gradient, ButtonLayerBuilder? explicitBuilder}) → ButtonLayerBuilder?

Builds a ButtonLayerBuilder that paints gradient behind the child.

m3eGradientFillLayer({required BorderRadius clipRadius, required Gradient gradient, required Widget? child, bool disabled = false}) → Widget

Paints gradient behind child, clipped to clipRadius.

m3eGradientForegroundBuilder({required BorderRadius clipRadius, WidgetStateProperty<Gradient?>? gradient, ButtonLayerBuilder? explicitBuilder}) → ButtonLayerBuilder?

Builds a ButtonLayerBuilder that applies gradient to foreground content.

m3eGradientForegroundLayer({required BorderRadius clipRadius, required Gradient gradient, required Widget child}) → Widget

Tints child with gradient via BlendMode.srcIn, clipped to clipRadius.

m3eGradientOutlineLayer({required BorderRadius clipRadius, required double width, required Widget child, Gradient? gradient, Color? color}) → Widget

Paints a stroke around child using clipRadius.

m3eGradientOverlayLayer({required BorderRadius clipRadius, required Gradient gradient, required double opacity, required Widget child}) → Widget

Paints gradient as a clipped state layer over child.

m3eGradientSpanRect({required GlobalKey<State<StatefulWidget>> hostKey, required BuildContext context, required Rect local}) → Rect

Maps local into the box of hostKey so siblings share one gradient span.

m3eGradientSurfaceBuilder({required BorderRadius clipRadius, WidgetStateProperty<Gradient?>? backgroundGradient, WidgetStateProperty<Gradient?>? overlayGradient, WidgetStateProperty<Gradient?>? outlineGradient, WidgetStateProperty<BorderSide?>? outlineSide, double outlineFallbackWidth = 1, ButtonLayerBuilder? explicitBuilder}) → ButtonLayerBuilder?

Fill, overlay, and outline for Material backgroundBuilder.

m3eOutlineWidth(BorderSide? side, {double fallback = 1}) → double

Width from side, or fallback when side is null or none.

m3eOverlayOpacityFor(Set<WidgetState> states) → double

Opacity for a gradient state layer from states.

m3eResolveGradientOverlay({required BorderRadius clipRadius, required Set<WidgetState> states, required Widget child, WidgetStateProperty<Gradient?>? overlayGradient}) → Widget

Resolves overlayGradient and paints it when the state layer is active.

m3eStatesForInteraction(M3EInteractionState state, {bool enabled = true}) → Set<WidgetState>

Maps an M3EInteractionState onto WidgetStates.

m3eUsesGradientOverlay(WidgetStateProperty<Gradient?>? overlayGradient) → bool

Whether overlayGradient should replace Material ink splash.
