flutter_form_builder set value of field programmatically not working
It is very simple and clarified in the official docs,
You can either change the value of one field at a time like so:
_formKey.currentState.fields['color_picker'].didChange(Colors.black);
Or multiple fields value like so:
_formKey.currentState.patchValue({ 'age': '50', 'slider': 6.7, 'filter_chip': ['Test 1'], 'choice_chip': 'Test 2', 'rate': 4, 'chips_test': [ Contact('Andrew', 'stock@man.com', 'https://d2gg9evh47fn9z.cloudfront.net/800px_COLOURBOX4057996.jpg'), ],});
