I want to show my own page on dropdown button tap, then item selected on page should be set as dropdown button value.
So basically, I need DropdownButton without any popup on tap. When I use onTap still default popup will be shown, how to prevent that?
why you don't use a button instead? or you can try to create an Inkwell put a container on its child and make it look like a button and write your code inside Inkwell OnTap(){}
1- Pass null to items parameter to disable the button.
2- You'll notice icon's color will be grey with disabled button, you can change it by setting color of the icon you send to icon parameter or send color directly to iconDisabledColor parameter.
3- You'll not use value parameter, instead you'll just use hint to show both your hint and your value. and update it using your state management after you pick new value from your own page.
4- Wrap your DropdownButton with GestureDetector or InkWell to show your own page when you tap on the button.
5- If you want to customize your DropdownButton shape, size and more. You can try my new package DropdownButton2. It's simple, easy, based on Flutter's core DropdownButton and have lots of features.

Hi I'm trying to create a screen that have bunch of container with a child of row that have a text and a Icon (the red one - can be seen on the image). So when I click the icon I want to show a dialog right next to the icon. I tried using aligned_dialog but the positioning is really hard to do, I want it to be instantly next to the icon just like the image.
Is there any package or widget that I can use to achieve this ?
You can check this package: https://pub.dev/packages/just_the_tooltip
It allow to specify a child of type Widget, so you can add what you want.
I'm using cardview on listview. And cardView has a icon.I wanna change icon color. When i click icon ,color is changed very well but whole listView is reloaded and goes to top of the listView. How can i change icon color withot refreshing listView?
connect the color to a variable and on an event change the variable using an terinary function then setState on the stateful widget.
Widgets vs helper method.

Here you can make a separate widget. That should be a stateful class. Otherwise, you can use any state management.
I am currently trying to create something like a TabBar. I created a horizontal ListView which should work as the TabBar and I my goal is, that one row fills itself with a list that contains the cards for the Tab I clicked on and refreshes when I click on another one. Is there a way to do that? It should look like this:

Did you look at Work with tabs, an introduction to TabBar, TabBarView and DefaultTabController?
You could also create it from scratch using a ListView with a Card wrapped in a GestureDetector or a ListTile, and detect taps on onTap, which would set the selected data and update state using setState.
I have a basic layout where I am using a stack widget to hold my other widgets.. I have a side toolbar, inside that I have a pen menu on click of which a popup should appear. When i am clicking the pen menu an alert dialog appears but not in the expected place, what i mean is...
I am expecting a dialog like the one in the below image. Do I need to use any plugin to create a dialog like this with a chevron mark?enter image description here
As you are using Alert dialog, it will by default be aligned in center of your screen. In order to achieve what you are trying to, I would suggest using a plugin like this.
I have a drawer in my
app. When I long tap it, "Open navigator menu" pops up. How can I change this? I already tried changing somethings in drawer.dart etc. but it didn't work.
it depends which action you use.
if you want different tap behaviour you can user GestureDetector
with Default drawer class, use Scaffold.of(context).openDrawer(); to open drawer with text in GestureDetector.
