A simple Flutter package to build dynamic Form

Dynamic Form

A simple StatefulWidget Form with dynamic content

Features

• Support TextField, TextArea, OptionPicker ( multiple/single select, Dropdown or Radio )

Getting started

• This is in early state library, so it will usually have breaking changes in next version

Usage

1. First, create a Controller extends DynamicFormController and design the Form in Controller constructor

class NewProjectDFController extends DynamicFormController {
  NewProjectDFController() {
    // 
    // design the form
    //
    formCreation = DynamicFormCreation(fields: [
      DynamicFormField(id: 'name',
          name: 'Project Name',
          fieldType: DynamicFormFieldTypes.TextField),
      DynamicFormField(id: 'desc',
          name: 'Project Description',
          fieldType: DynamicFormFieldTypes.TextArea),
      DynamicFormField.createDropdownSelect('category', 'Category', items: [
        'Application Builder',
        'Story Builder',
        'Course Builder',
        'Marketing Campaign Builder'
      ])
    ]);
  }
}

2. Then, declare an instance of Controller and bind state in initState()

// declare the Controller
NewProjectDFController newProjectFormController = NewProjectDFController();

// bind state
@override
void initState() {
  super.initState();
  newProjectFormController.bindState(reloadForm: () => setState(() {}));
}

3. use it as Dialog content or as other Widget in build()

showAddNewProjectDialog() {
  showDialog(context: context, builder: (_) => AlertDialog(
    title: Text("Create new Project"),
    content: newProjectFormController.buildForm(context),
    actions: [ElevatedButton(onPressed: () {
      bool isValid = newProjectFormController.validateFields();
      if (isValid) {
        Navigator.pop(context);
        var model = newProjectFormController.formValues;
        debugPrint("New Project Model:");
        debugPrint(jsonEncode(model));
      }
    }, child: Text("Create"))
    ],
  ));
}
