applyDefaults method

InputDecoration applyDefaults(
  1. Object inputDecorationTheme
)

Used by widgets like TextField and InputDecorator to create a new InputDecoration with default values taken from the inputDecorationTheme.

Only null valued properties from this InputDecoration are replaced by the corresponding values from inputDecorationTheme.

Implementation

InputDecoration applyDefaults(Object inputDecorationTheme) {
  // TODO(bleroux): Clean this up once the type of `inputDecorationTheme` is changed to `InputDecorationThemeData`
  if (inputDecorationTheme is! InputDecorationTheme &&
      inputDecorationTheme is! InputDecorationThemeData) {
    throw ArgumentError(
      'inputDecorationTheme must be either a InputDecorationThemeData or a InputDecorationTheme',
    );
  }
  final InputDecorationThemeData theme = (inputDecorationTheme is InputDecorationTheme)
      ? inputDecorationTheme.data
      : inputDecorationTheme as InputDecorationThemeData;
