Description

Only type-based completion

By default, AppCode suggests completion for symbols regardless of their types. With this approach, in complicated cases the list shows multiple completion variants.

To make completion more precise, select the checkbox. The completion list will strongly depend on the AppCode inference. As a result, the list may remain empty in case of poor inference.

Suggest items with optional chaining for nullable types

By default, AppCode suggests completion for symbols with the optional chaining operator (?). To suppress showing such suggestions, clear the checkbox.

Expand method bodies in completion for overrides

By default, when you want to override a method from the parent class or interface and select this method from the list of completion suggestions, AppCode automatically adds parameters, generates a super() call, and adds the type information, if possible.

Clear the Expand method bodies in completion for overrides checkbox to suppress automatic generation of method bodies for overrides during completion.

Completion of names
  • Suggest variable and parameter names: By default, the checkbox is cleared. When it is selected, AppCode suggests names for new variables and parameters during their declaration. These suggestions are based on the names of classes, types, and interfaces that are defined in your project, in the libraries you are using, and in standard APIs.

  • Suggest names for class fields

    The option is by default turned off.

  • Add type annotations for suggested parameter names: Select this checkbox to supply each completion suggestion with information on its type.

    The checkbox is available only when the Suggest variable and parameter names checkbox is selected.

Dart

Item

Description

Insert default argument values in completions

By default, when you select and apply a completion suggestion, AppCode inserts default argument values so you only need to fill in the field in the inserted template.

Clear the checkbox to suppress such behavior and fill in the arguments yourself.
