$field = ee('Model')->make('fluid_field:FluidField');
// Assign required values.
$field->entry_id = 19; // The Entry we want to associate this fluid field with.
$field->fluid_field_id = 15; // The Fluid Field ID itself.
$field->field_id = 9; // The Text Field ID to add.
$field->field_data_id = 4; // The row of data in the text field to use.
$field->order = 5; // Set the order relative to other fields within the fluid field. Omitting will put the new field first.
