Computes the changes for this producer using builder.

This method should not modify fixKind.

Implementation

@override

  final widgetExpr = node.findComponentExpression;

    return;
  }

  final widgetType = widgetExpr.staticType;

    return;
  }

  final widgetSrc = utils.getNodeText(widgetExpr);
  final parentClassElement = await sessionHelper.getClass(
    noctermUri,
    'Padding',
  );
  if (parentClassElement == null) {
    return;
  }

  await builder.addDartFileEdit(file, (builder) {
    // var eol = builder.eol;
    final keyword = widgetExpr.inConstantContext ? '' : ' const';
    final codeStyleOptions = getCodeStyleOptions(unitResult.file);
    final paddingStr = codeStyleOptions.preferIntLiterals ? '8' : '8.0';

    builder.addReplacement(range.node(widgetExpr), (builder) {
      builder.writeReference(parentClassElement);
      builder.write('(');
      builder.writeln();

      builder.write(indentNew);
      builder.write('padding:$keyword EdgeInsets.all($paddingStr),');
