This is an animated power point presentation on topic flutter. Flutter is a programming framework for cross-platform application development. Which is supported with dart language.
This slide includes all the theoretical information related to flutter such as widgets of flutter, animations in flutter, Styling properties, competition with other languages and framework, etc.
An Activity is an application component that provides a screen with which users can interact in order to do something, such as dial the phone, take a photo, send an email, or view a map.
Each activity is given a window in which to draw its user interface. The window typically fills the screen, but may be smaller than the screen and float on top of other windows.
An application usually consists of multiple activities that are loosely bound to each other. Typically, one activity in an application is specified as the "main" activity, which is presented to the user when launching the application for the first time. Each activity can then start another activity in order to perform different actions.
Each time a new activity starts, the previous activity is stopped, but the system preserves the activity in a stack .
When a new activity starts, it is pushed onto the back stack and takes user focus.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Form Elements Tutorial (Contd.)- Custom Button
We’ll create an image button with 3 states Using the Button widget and an XML file that
defines three different images to use for the
different button states. When the button is
Normal Focused Pressed pressed, a short message will be displayed.
1. Copy the images on the right into the res/drawable/ directory of your project. These will
be used for the different button states.
2. Create a new file in the res/drawable/ directory named android_button.xml.
Insert the following XML:
This defines a single drawable resource, which will change its image based on the current state
of the button.
6. User Interface
Android Widget Toolbox
Form Elements Tutorial (Contd.)- Custom Button
3. Open the res/layout/main.xml file and add the Button element:
The android:background attribute specifies the drawable
resource to use for the button background (which, when saved at res/drawable/android.xml,
is referenced as @drawable/android). This replaces the normal background image used for
buttons throughout the system. In order for the drawable to change its image based on the
button state, the image must be applied to the background

Form Elements Tutorial (Contd.)- Radio Button
In this section, you will create two mutually-exclusive radio buttons (enabling one disables the
other), using the RadioGroup and RadioButton widgets.
When either radio button is pressed, a toast message will be displayed.
1. Open the res/layout/main.xml file and add two RadioButtons, nested in a RadioGroup
(inside the LinearLayout):
It's important that the RadioButtons are grouped together by the RadioGroup element so that
no more than one can be selected at a time. This logic is automatically handled by the Android
system. When one RadioButton within a group is selected, all others are automatically deselected
15. User Interface
Android Widget Toolbox
Form Elements Tutorial (Contd.)- Radio Button
2. To do something when each RadioButton is selected, you need an View.OnClickListener.
In this case, you want the listener to be re-usable, so add the following code to create a new
member in the HelloFormStuff Activity
3. Now, at the bottom of the onCreate() method, add the following:
17. User Interface
Android Widget Toolbox
Form Elements Tutorial (Contd.)- Toggle Button
In this section, you'll create a button used specifically for toggling between two states, using
the ToggleButton widget. This widget is an excellent alternative to radio buttons if you have
two simple states that are mutually exclusive ("on" and "off", for example).
1. Open the res/layout/main.xml file and add the ToggleButton element (inside the
LinearLayout):
18. User Interface
Android Widget Toolbox
Form Elements Tutorial (Contd.)- Toggle Button
2. To do something when the state is changed, add the following code to the end of the
onCreate() method:
This captures the ToggleButton element from the layout, then adds an View.OnClickListener.
The View.OnClickListener must implement the onClick(View) callback method, which defines
the action to perform when the button is clicked. In this example, the callback method checks
the new state of the button, then shows a Toast message that indicates the current state.
20. User Interface
Android Widget Toolbox
Form Elements Tutorial (Contd.)- Rating Bar
In this section, you'll create a widget that allows the user to provide a rating, with the
RatingBar widget.
