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.maybeParseDouble(map['bottom']),
      curve: map['curve'] ?? Curves.linear,
      duration: JsonClass.maybeParseDurationFromMillis(
        map['duration'],
      )!,
      end: JsonClass.maybeParseDouble(map['end']),
      height: JsonClass.maybeParseDouble(map['height']),
      onEnd: map['onEnd'],
      start: JsonClass.maybeParseDouble(map['start']),
      top: JsonClass.maybeParseDouble(map['top']),
      width: JsonClass.maybeParseDouble(map['width']),
    );
  }

  return result;
}
