Hello I'm having trouble changing my Logo depending on the Theme. In Dark Theme I can't see the black outlines of my logo, whilst I can on white background in light theme mode.

Here's the main.dart Code Line:

I am having problems restarting the emulator after turning it off. Restarting android studio - doesn't help. Restarting my computer helps. I also cannot find and [stop this process] through the task manager. So that I can not reboot. By the way, the error is displayed with a typo. Help. Who faced such a problem, how to solve it?

I am trying to build a cinema app with flutter. The structure is as follows:

• in each city there are a bunch of cinemas
• in a cinema there are a bunch of showrooms(salle in french)
• in a showroom(salle in french) there are five display sessions or projections, these projections are of the same film.

because the projections are of the same movie (a showroom displays the same movie in different time(e.g projections) by design), when I click on any of the projections in a showroom I should have the same posture of the same film, not a different posture in each projection.

However I get a different film posture in each projection, and I don't know what is causing this.

I am using a rest api that I created with Spring, and I am certain that the problem is not from my back-end because I am using it in an angular web app and it's working perfectly.

This is a layout of my application

this is what happened when I click on two projection of the same showroom( notice that the posture changes when it shouldn't.

and here is the code of the showroom page (salles-page.dart)

I have having 3 error about the object cant be assigned to parameter including int, string and double . I'm trying to fetch data to create a chart-bar to display and process the data.it fetches from another widget called Transaction.

So, I have a TextField that looks like:

I have a class SocialAuth, which holds some common properties of the AuthModel class. Now I want to dynamically update the instance of AuthModel based on the object of SocialAuth class.

I'm looping over the .toJson() of SocialAuth and trying to update the property of _authModel (Instance of AuthModel) dynamically.

ERROR IS - The operator '[]=' isn't defined for the type 'AuthModel'.

SocialAuth Class

I have following json in my API response :

I'm just working through this whole null-safety mode with my Flutter project and unsure what the difference is with ? and ! in calls to object methods.

For example, the hint was to add a ! conditional. Here's an example I have right now, and I'm unsure if this should be a ? or a ! at the findNbr!.replaceAll().

I am having trouble trying to iterate over a JSON array of objects from a remote URL using Flutter's FutureBuilder.

My goal is to:

• Fetch JSON data from an API
• Output the data into a 2 column gridview layout

The JSON data is an array of objects(or a List of Maps in dart), the objects have simple string data.

I know that I need to build a future to fetch the data from the API and decode the JSON, then I need to create a FutureBuilder to output the List data into my Gridview Builder. That is what I have tried to do in my code below.
