Parameters
| Parameter |
Type |
Description |
| varName |
string | null | typeof Field.SKIP_SETUP |
The default name for the variable. If null, a unique variable name will be generated. Also accepts Field.SKIP_SETUP if you wish to skip setup (only used by subclasses that want to handle configuration and setting the field value after their own constructors have run). |
| validator |
FieldVariableValidator |
(Optional) A function that is called to validate changes to the field's value. Takes in a variable ID & returns a validated variable ID, or null to abort the change. |
| variableTypes |
string[] |
(Optional) A list of the types of variables to include in the dropdown. Will only be used if config is not provided. |
| defaultType |
string |
(Optional) The type of variable to create if this field's value is not explicitly set. Defaults to ''. Will only be used if config is not provided. |
| config |
FieldVariableConfig |
(Optional) A map of options used to configure the field. See the [field creation documentation]https://developers.google.com/blockly/guides/create-custom-blocks/fields/built-in-fields/variable#creation for a list of properties this parameter supports. |
