I’m building a mock writing test app with flutter. I need to display the writing prompt in the top of the screen while the user can write the essay below.
I’d like to allow the user to select the key words in the prompt and highlight them to help them stay focused on the topic while writing. How can it be achieved?
simply do this
String title ="<mark>"+_SelectedWordToSearch+"<mark>"
enter code here

I'm trying to create an text field which will flow to the top of the screen when the user starts typing and will show results in a list beneath it. I'm already gathering the results matching the users query into a list from Firebase, all I need is to somehow display the data. I would like to have the search results displayed under the text field in a similar way as google play is showing the search history. Any ideas witch widget should I use, so it would pop under the text field when the user starts typing?
you can use this package (material_floating_search_bar) to obtain this behavior.
at the moment i try to revised my password textfield.
I'm adding passwort rules.
For Example the password must allways 8 letters length...
Now i want a dialog for more useful information for the user.
I found in the internet a nice example.
Here the example:
My problem, i don't know how i can create this dialog in flutter.
I found the alertDialog in internet, but the background changes and the dialog close after the user klick on screen.
Here a emxample from AlertDialog:
Anyone have a idea how i can create a dialog like the first example.
The dialog should always visible.
Also if the user klick on screen.
But it should also allow the user to edit the textfield.
Many thx (:
I think the easiest way is to toast when the user clicks on submit button you can show this or you can show in text form field error text so user gets specific text like "Enter your name".
I am developing an application for the desktop with Flutter. I had to implement the form with multiple input fields. I really need to make the whole focus flow and I have used the FocusNode class to move from one input field to another. Everything is based on the submit event, so when I hit the Enter button on the keyboard it moves to the next field. It is pretty ok, but I have to change it from Enter key to Tab key which is more natural for the desktop users. Have you got any idea what can I do here to achieve such a result? Is there a way to trigger the submit event by different key (than Enter)?
This bug is for making it easy to bind keys to actions. Once that's complete, one of the intended use cases is to add tab support for form field navigation. There's been a lot of work in that area recently, so I wouldn't recommend putting time into working around this yourself.
I am trying to display a word suggestion list when ctl+space entered as in eclipse.
For that I need to know the location where user has entered ctrl+space so that i can display the suggestion list exact below to the word user just entered.
I see ways to get the mouse cursor position , But isnt there a way to get the keyboard button pressed position ,
I am writing inside textArea, I tried getCursor, but it gives me the no of word on which user entered ctrl+space. Not the location as per the Window.
Any idea
thanks
There is no reliable, accurate and cross-browser way to do it with TextArea.
You can experiment with a RichTextArea (you don't have to provide a toolbar for rich text features) and its getFormatter().insertHTML() method. It will insert a new HTML element at a cursor position. You can insert a list of suggested words, that you can style to look anyway you like, or you can insert an empty div and try to show a panel relative to it.
Or you can use a different UI approach. Create a panel with a fixed position relative to your TextArea and show your suggested words there - similar to the way good smartphone keyboards show suggested words just above the keyboard itself. Once your users realize that suggested words always show up in the same place, they may even like this design better.
I need to focus a text input into the Facebook login popup. I am using a virtual keyboard to simulate a physical one, but when I click a key, the text input lose focus and the letter is not written into the field.
How could I maintain the focus in the text input?
I'm not sure if creating your own virtual keyboard is a smart idea since all mobiles already have one in there, you just need to set useSoftKeyboard in Flex.
Also, you can always remove focusability to your components by setting focusEnabled and hasFocusableChildren to false.
I finally came to another solution... Using getElementsByTagName('theElementID'), I could get a reference to the textInputs in the browser, and I could modify its attributes...
For example,
emailStringObject =this.html.htmlLoader.window.document.getElementById('email');
emailStringObject.value="example#correo.com"
