buildRoute(WidgetNodeSpec spec, {Map? state}) → MaterialPageRoute

Creates a MaterialPageRoute for a given Screen spec.

buildScreen(BuildContext context, WidgetNodeSpec spec, {Map? state}) → Widget

Builds a LowderScreen based on its spec.

buildWidget(BuildContext context, Map spec, Map state, Map? parentContext) → Widget

Transforms a Map spec to a WidgetNodeSpec spec and executes buildWidgetFromSpec.

buildWidgetFromSpec(BuildContext context, WidgetNodeSpec spec, Map state, Map? parentContext) → Widget

Executes a Widget build from a spec.

createWidget(BuildContext context, WidgetNodeSpec spec, Map state, Map? parentContext) → Widget

getCheckboxValidator(Map spec) → CheckboxValidationFunction

Convenience method returning a generic validator for bool input Widgets.

getEvaluatorContext(Object? value, Map state, Map? specContext) → Map

Returns a Map with the evaluation context used when sanitizing properties of a NodeSpec. Used to resolve properties that use placeholders as values, like "${state.firstName}" or "${env.api_uri}".

getGlobalBlocConsumer(BlocBuilderFunction builder, {BlocListenerFunction? listener, WidgetNodeSpec? node}) → Widget

Convenience method to instantiate a GlobalBlocConsumer and facilitate overriding.

getLocalBlocConsumer(BlocBuilderFunction builder, {BlocListenerFunction? listener}) → Widget

Convenience method to instantiate a LocalBlocConsumer and facilitate overriding.

getPropertySchema(String type) → Map<String, EditorPropertyType>

Returns a Widget's propery schema.

getStringValidator(Map spec) → StringValueValidationFunction

Convenience method returning a generic validator for string input Widgets.

getTemplate(String? id) → Map

Returns the Template node with the given id from the Model.

handleDecorator(BuildContext context, Widget widget, WidgetNodeSpec spec) → Widget

Handles convenience 'decoration' property.

handleExpanded(BuildContext context, Widget widget, WidgetNodeSpec spec) → Widget

Handles convenience 'wrapExpanded' property.

handleHero(BuildContext context, Widget widget, WidgetNodeSpec spec) → Widget

Handles convenience 'hero' property.

handleMargin(BuildContext context, Widget widget, WidgetNodeSpec spec) → Widget

Handles convenience 'margin' property.

handleSafeArea(BuildContext context, Widget widget, WidgetNodeSpec spec) → Widget

Handles convenience 'safeArea' property.

handleVisibility(BuildContext context, Widget widget, WidgetNodeSpec spec) → Widget

Handles convenience 'visible' property.

hideActivityIndicator() → void

Hides the activity indicator.

internalBuildScreen(BuildContext context, WidgetNodeSpec spec, Map screenState) → Widget

Builds a LowderScreen based on its spec.

loadWidgets(IWidgets widgets) → void

Schema loading

mergeMaps(Map map1, Map map2) → void

Utility method to merge two Maps.

mergeTemplateAndState(WidgetNodeSpec spec, Map template, Map state, Map parentContext) → void

Sanitizes the properties of a spec using template and string evaluation. E.g.: a property valued "${state.firstName}" will have its value replaced with the state's "firstName" key value.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

postBuild(BuildContext context, Widget widget, WidgetNodeSpec spec) → Widget

Handles generic convenience properties from a spec, like decoration, margin or visibility.

preBuild(BuildContext context, WidgetNodeSpec spec, Map state, Map? parentContext) → void
