A theme in Flutter is important as it represents your app’s style, look and feel. However, it should be created using the Flutter app, such as dark and light modes. It is known as Flutter Theming.
Of course, the light and dark Theme with custom color must be set to hire flutter developer without any hassles. It includes the app theme and default color attribute accordingly. Thus, it should be identified with the live project and required to add the custom app color for branding.
To successfully implement Flutter Theming, you must find default options by setting color themes. It has to add basic value, hence suitable for holding app branding. It should be implemented based on the flutter light mode and dark mode accordingly.
Create flutter project
Adding a riverpod package should be implemented based on state management. It should be admired and needs to be optimized based on the convenient options. They are ready to go ahead and include the following things to enable custom flutter Theming forever.
Step 1: Create a Light/Dark Theme
When creating a light and dark mode, we have to use themedata class and customize colors and other properties to induce. They also capture getting themeDate based on the selected light and dark themes. It includes values and can approach them with the background color to change, and the app bar theme should be selected Theme.
Step 2: Create Provider for Theme State Using River-pod
It must use River pod to control the app theme state, and it can only control the light or dark theme with a boolean value. As a result, it provides state services to enter the river pod-based theme and begin customizing Flutter themes to your specifications.
Step 3: Use the Theme in the App
They use riverpod in the project and can wrap my app with provider scope and need to change Theming for your needs. They will customize based on the consumer widget and be able to focus on the object to set out building methods and access any riverpod to ref.watch and Theme should be optimized based on the updates in the app design with basic color Theming.
Step 4: Add Custom Color
It works mainly by picking the same color and controlling it based on the icons and texts. They come with functionalities and explore theme extensions. In addition, the Theme should be explored by focusing on theme extension and adding necessary fields to customize options for your desires.
Now, add the extension attribute to control the creating method for the app theme and define the Theme according to the colors. They come with more options by focusing on colors by widget and using colors context color1. It will specify the icon color and fetch the color from the listTiletheme.
Step 5: Full Source Code
If you run an app for controlling themes, it should be under full source code. However, it consists of a theme for a parent to include a material app widget. In addition to this, it will specify the themedata.light() Theme and UI will not change by default changes in the Theme applied in the light Theme.
Why Dark mode?
Devices with OLED (Organic light emitting diodes) and AMOLED (Active Matrix Organic light emitting diodes) screens benefit from dark mode settings because they use less power and save battery life.
On your OLED display, each pixel is illuminated. As a result, when the background of your display is white, all of the pixels light up, requiring more power.
The Dark Theme has been applied here, so our UI will update if we switch the Device theme from Light to Dark in Settings. Be the default, and the Flutter framework will change all whites to black and all blacks to white. Check here and know about Multi-Themes Using Riverpod in Flutter.
Add Theme provider in main.dart.
In Myapp class, the user has to assign the custom dark and light Theme to darktheme and theme attributes. They will develop a good solution that includes a theme notifier.
Get thememode() and add to modify a theme based on the thememode set by the main.dart. It includes Themes by focusing on selected Themes in shared preference and updating the themenotifier based on the applications to change themes accordingly.
On the other hand, setting the screen should be given by changing the Theme to the system, such as dark or light mode. Then, click ok, select Theme in shared preferences, and update the themenotifier with the application about theme changes.
Of course, theme properties should be valid and set out themedata objects with a salient package. It should be flexible enough to change them by creating two light and dark themes.
They include creating a new file named by app theme.dart and property are accepting the themedata object for ahead on creating custom.
Here the thought is to communicate the subject change when the client changes. We will now require a package that can accomplish that. Therefore, open the pubspec.yaml file and incorporate the “provider” package.
Install the package by running the Flutter packages get command inside your project. We must now write a class and a method to broadcast theme changes. Therefore, let’s create a brand-new class called “AppStateNotifier.”
Within this class, the HomeApp is surrounded by a ChangeNotifierProvider Widget that receives changes and sends them to the “Consumer” widget, where they are consumed and used to make changes.
The appState variable updates the “themeMode” property in the above code. The Listeners, then the Consumer Widget, will receive the boolean value true when the Switch widget is activated.
Update the Text Themes
Now, it has to set up an application which uses theme() by focusing with a widget and needs to be text themes. It will depend on the custom themes and mainly applicable for noticing context for updating flutter apps.
From the above, you know that Flutter Theming, such as light and dark modes, should be configured well. This article helps choose the right Theme for Flutter app development.
They consider the vital role and maintain proclaimed in apptheme class with code design and value for text. Depending on the requirements, the Flutter developer will choose a dark or light theme.
