fromDynamic static method
JsonAnimatedPositionedDirectionalBuilder?
fromDynamic(
- dynamic map, {
- JsonWidgetRegistry? registry,
Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
{
"bottom": <double>,
"curve": <Curve>,
"duration": <int; millis>,
"end": <double>,
"height": <double>,
"onEnd": <VoidCallback>,
"start": <double>,
"top": <double>,
"width": <double>,
}
As a note, the Curve and VoidCallback cannot be decoded via JSON. Instead, the only way to bind those values to the builder is to use a function or a variable reference via the JsonWidgetRegistry.
Implementation
static JsonAnimatedPositionedDirectionalBuilder? fromDynamic(
dynamic map, {
JsonWidgetRegistry? registry,
}) {
JsonAnimatedPositionedDirectionalBuilder? result;
if (map != null) {
result = JsonAnimatedPositionedDirectionalBuilder(
bottom: JsonClass.parseDouble(map['bottom']),
curve: map['curve'] ?? Curves.linear,
duration: JsonClass.parseDurationFromMillis(
map['duration'],
)!,
end: JsonClass.parseDouble(map['end']),
height: JsonClass.parseDouble(map['height']),
onEnd: map['onEnd'],
start: JsonClass.parseDouble(map['start']),
top: JsonClass.parseDouble(map['top']),
width: JsonClass.parseDouble(map['width']),
);
}
return result;
}
