fromDynamic static method

JsonButtonBarBuilder? 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:

{
  "alignment": "<MainAxisAlignment>",
  "buttonAlignedDropdown": "<bool>",
  "buttonHeight": "<double>",
  "buttonMinWidth": "<double>",
  "buttonPadding": "<EdgeInsetsGeometry>",
  "buttonTextTheme": "<ButtonTextTheme>",
  "layoutBehavior": "<ButtonBarLayoutBehavior>",
  "mainAxisSize": "<MainAxisSize>",
  "overflowButtonSpacing": "<double>",
  "overflowDirection": "<VerticalDirection>"
}

Implementation

static JsonButtonBarBuilder? fromDynamic(
  dynamic map, {
  JsonWidgetRegistry? registry,
}) {
  JsonButtonBarBuilder? result;

  if (map != null) {
    result = JsonButtonBarBuilder(
      alignment: ThemeDecoder.decodeMainAxisAlignment(
        map['alignment'],
        validate: false,
      ),
      buttonAlignedDropdown: map['buttonAlignedDropdown'] == null
          ? null
          : JsonClass.parseBool(map['buttonAlignedDropdown']),
      buttonHeight: JsonClass.maybeParseDouble(map['buttonHeight']),
      buttonMinWidth: JsonClass.maybeParseDouble(map['buttonMinWidth']),
      buttonPadding: ThemeDecoder.decodeEdgeInsetsGeometry(
        map['buttonPadding'],
        validate: false,
      ),
      buttonTextTheme: ThemeDecoder.decodeButtonTextTheme(
        map['buttonTextTheme'],
        validate: false,
      ),
      layoutBehavior: ThemeDecoder.decodeButtonBarLayoutBehavior(
        map['layoutBehavior'],
        validate: false,
      ),
      mainAxisSize: ThemeDecoder.decodeMainAxisSize(
        map['mainAxisSize'],
        validate: false,
      ),
      overflowButtonSpacing:
          JsonClass.maybeParseDouble(map['overflowButtonSpacing']),
      overflowDirection: ThemeDecoder.decodeVerticalDirection(
        map['overflowDirection'],
        validate: false,
      ),
