DropdownButtonFormField & Validation from API
Requirements :
– API Service
– Object Model
Developer Recommendation : NB!!! – Use QuickType for your model.
(You need an already working api with a JSON response for quicktype) https://app.quicktype.io/
– DropDownMenuItem
NB!!! – The DropDownMenuItem must be wrapped in a form widget to implement validation.
HINT : Avoid casting variable types such as <String> or <List> or <Object> until your list is actually working. In the DropdownButtonFormField Snippet, you will see no types are declared.
Step 1 :
Configuration :
(On your page.dart or screen.dart)
You need to include these.
1 : Your Model from QuickType
// Model import './model/support_fields_model.dart'; // API import 'package:project_name/api/support_fields_service.dart'; // Includes import 'package:flutter/material.dart';
DropdownButtonFormField Snippet :
child: Form( key: globalFormKey, Container( child: DropdownButtonFormField( hint: Text("-- Select Query --"), value: querySelect, validator: (querySelect) => querySelect == "-- Select Query --" ? 'Select Query Required' : null, onChanged: (newValue) { setState(() { dropDownButtonCallback( newValue, "select_query"); }); }, items: querySelectOptions .map<DropdownMenuItem>((map) { return DropdownMenuItem( value: map.name, child: Text(map.name), ); }).toList(), ), // DropdownButtonFormField ), // Container ), // Form
Excell Calculations for Text after and Before Space
Excel give characters after space
If you want to extract the text after space only, use this formula =MID(A1,FIND(" ",A1)+1,256)
Excel give characters before space
Extract text before or after space with formula in ExcelYou can quickly extract the text before space from the list only by using formula. Select a blank cell, and type this formula =LEFT(A1,(FIND(" ",A1,1)-1)) (A1 is the first cell of the list you want to extract text) , and press Enter button.
