AdaptyCustomAsset.linearGradient constructor
- required LinearGradient gradient,
A linear gradient. The flow receives its LinearGradient.colors, LinearGradient.stops, LinearGradient.begin and LinearGradient.end.
AlignmentDirectional values, and alignments that combine Alignment with AlignmentDirectional
(for example the result of AlignmentGeometry.add), are resolved left-to-right whatever the ambient
Directionality, so start is the left edge.
The gradient is not mirrored when the flow is shown in a right-to-left localization. On both iOS and
Android the flow lays out its text and controls right-to-left but draws the gradient exactly as in a
left-to-right flow, whether LinearGradient.begin and LinearGradient.end are Alignment or
AlignmentDirectional values. To mirror it yourself, resolve the alignments for right-to-left before
passing them, for example AlignmentDirectional.centerStart.resolve(TextDirection.rtl).
LinearGradient.transform, and any LinearGradient.tileMode other than TileMode.clamp, are not supported: they are ignored and a warning is logged.
LinearGradient.stops, when given, must have as many entries as LinearGradient.colors, and every
stop and alignment coordinate must be finite. Otherwise AdaptyUI.createFlowView fails with an
AdaptyError with code AdaptyErrorCode.wrongParam, and AdaptyUIFlowPlatformView throws an
ArgumentError when it builds.
Implementation
const factory AdaptyCustomAsset.linearGradient({
required LinearGradient gradient,
}) = AdaptyCustomAssetLinearGradient;
