fromDynamic static method
Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
{
"curve": "<Curve>",
"data": "<ThemeData>",
"duration": "<int; millis>",
"onEnd": "<VoidCallback>"
}
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 JsonAnimatedThemeBuilder? fromDynamic(
dynamic map, {
JsonWidgetRegistry? registry,
}) {
JsonAnimatedThemeBuilder? result;
if (map != null) {
result = JsonAnimatedThemeBuilder(
curve: map['curve'] ?? Curves.linear,
data: ThemeDecoder.decodeThemeData(
map['data'],
validate: false,
)!,
duration: JsonClass.maybeParseDurationFromMillis(
map['duration'],
) ??
kThemeAnimationDuration,
onEnd: map['onEnd'],
);
}
return result;
}
