| `type` | <p>**string**</p><p>Required parameter.</p><p>The value must always be `animator_start`.</p><p>Available platforms: iOS, Android, web.</p> |
| `direction` | <p>**string**</p><p>Animation direction. Determines whether the animation should be played forward, backward, or alternate between forward and backward.</p><p>Possible values: `normal`, `reverse`, `alternate`, `alternate_reverse`.</p><p>Available platforms: iOS, Android, web.</p> |
| `duration` | <p>**int**</p><p>Animation duration in milliseconds.</p><p>Restriction for the value `x`: `x >= 0`.</p><p>Available platforms: iOS, Android, web.</p> |
| `end_value` | <p>**object**</p><p>Overrides the value that will be set after the animation finishes.</p><p>The value has the type `div-typed-value`.</p><p>Available platforms: iOS, Android, web.</p><p>List of possible values:<li>[string_value](string_value.md#string_value)</li><li>[integer_value](integer_value.md#integer_value)</li><li>[number_value](number_value.md#number_value)</li><li>[color_value](color_value.md#color_value)</li><li>[boolean_value](boolean_value.md#boolean_value)</li><li>[url_value](url_value.md#url_value)</li><li>[dict_value](dict_value.md#dict_value)</li><li>[array_value](array_value.md#array_value)</li></p> |
