initialValue Cannot be set. Change to of initialValue from int to List<String> #2

Closed randaleWatson closed 5 years ago

randaleWatson commented 5 years ago

I would be nice to populate the selected values. Currently the MultiSelect.initialValue is set to int type so there cannot be a list of strings sent to be pre-selected. This can be useful when one wants to hydrate the selected options in a form when a user reopens a page that has a list of stored values.

Thank you for your work on this widget.

@randaleWatson Thanks for your feedback. Right now the widget support passing the initial values but instead of initialValue it uses value property.

So, the example that we have can be something like below MultiSelect( ... ... ... value: [2,3] // instead of null )

But I take your suggestion and will make it more uniform to other standard form fields. Apart from this I have more updates to be pushed for this widget.

Thank you once again for using it and posting your feedback.

I have set value: [1,3], but it's not working, this is my code:

        MultiSelect(
            autovalidate: false,
            titleText: "Paramédicaux",

            dataSource: [
              {
                "display": "Dorsaf Mansouri",
                "value": 1,
              },
              {
                "display": "Imed Trabelsi",
                "value": 2,
              },
              {
                "display": "Maha Jandoubi",
                "value": 3,
              },
            ],
            hintText: "Appuyez pour sélectionner un ou plusieurs",
            textField: 'display',
            valueField: 'value',
            filterable: true,
            required: true,
            value: [1,3],
            onSaved: (value) {
              print('The value is $value');
            }
          )

Still get an empty view, nothing is selected !

@SlimenTN Please use initialValue: [1,3]; // for setting initial values

The full code goes like this -

MultiSelect( autovalidate: false, titleText: "Paramédicaux",

                dataSource: [
                  {
                    "display": "Dorsaf Mansouri",
                    "value": 1,
                  },
                  {
                    "display": "Imed Trabelsi",
                    "value": 2,
                  },
                  {
                    "display": "Maha Jandoubi",
                    "value": 3,
                  },
                ],
                hintText: "Appuyez pour sélectionner un ou plusieurs",
                textField: 'display',
                valueField: 'value',
                filterable: true,
                required: true,
                initialValue: [1,3],
                value: null,
                onSaved: (value) {
                  print('The value is $value');
                }
            )
