For consistency and efficiency in Flutter development, predefined components play a crucial role. Before embarking on creating a new widget, it’s beneficial to explore the existing library of predefined components.

​
Text Components

A variety of text components, such as RunningText, cater to different contexts and semantic purposes. These components ensure uniform styling and behavior throughout the app. 
RunningText(
  label: 'Welcome to Gymo!',
  style: TextStyle(
    color: Colors.blue,
    fontWeight: FontWeight.bold,
  ),
)
  • Best Practice: Opt for predefined text components to maintain a cohesive design language across your app.

​
Input Components

Predefined input components, like InputFormField, come with inherent styles and functionalities, such as validation and label management. 
InputFormField(
  labelText: 'Email',
  placeholder: 'Enter your email',
  validator: (value) {
    if (value == null || value.isEmpty) {
      return 'Email is required';
    }
    return null;
  },
)
  • Best Practice: Utilize these input components for uniformity and built-in functionalities, avoiding repetitive code.

​
Customization

While predefined components offer a solid foundation, they also support customization. You can modify their properties, like style in RunningText or validator in InputFormField, to meet specific requirements.

​
Conclusion

By consistently using predefined components, developers can ensure a uniform and maintainable codebase. This not only streamlines the development process but also simplifies future updates and modifications. Always refer to the component documentation for details on available widgets and their usage.
