Introduction
Jetpack Compose is a world where designing reusable and customizable UI components is essential. Within this realm, there are two primary ways to approach modifiers. Initially, one method was born of necessity during the early stages of our design system. As the design structure found its feet, a more flexible approach emerged. This article will delve into this journey, from discouraging modifier modifications to embracing the notion of applying modifiers to the given Modifier parameter.
The Early Days: Discouraging Modifier Modifications
In a prior discussion, the focus was on the hurdles we faced during the infancy of our design system. The main hindrance was the rampant usage of modifiers within our composable functions. Take, for instance, a basic “primary button” composable that was designed to receive a Modifier as a parameter. Each developer had their unique imagination for how this button should look. While some envisioned it tall, others saw it in hues of blue. This constant cycle of alterations made managing and customizing our UI components an uphill battle.
The Emergence of Flexibility
Fast forward to today, and our design system stands robust and mature. Despite that, my conviction that some modifier alterations can be beneficial, especially for usability, remains strong. A colleague, Amin, brought forth a different viewpoint. He suggested that not all modifier modifications are problematic. Certain modifications, like those relevant to click behavior, can actually amplify usability and decrease complexity.
The Clarification
Sticking to the principle of “Avoid Applying Modifiers to the Provided Modifier” does not suggest that everything should be defined within the calling composable. The purpose of the input modifier is to influence the layout of the component. Details specific to the component should be determined within the component itself.
To illustrate, consider a button displayed on the screen, possibly with some padding or in a specific location, say, at the bottom of a box. Such layout-related tasks fall under the purview of the parent composable. On the other hand, aspects such as the radius of the button, its color, or the text it displays are intrinsic to the button component’s functionality. This doesn’t imply that everything should be delegated to the component.
As can be seen in the SimpleButton composable, I’ve outlined several parameters to modify the button design and behavior. However, it’s the SimpleButton component’s responsibility to apply the modifier based on its particular needs. This technique not only clarifies the component’s role but also enhances its reusability for developers. It eradicates the need to continuously mull over both parent and component modifiers every time the button is utilized. This saves precious development time and encourages a shared UI language between designers and developers, fostering effective collaboration and streamlined workflows.
Modifiers Modification
This change in perspective did not spark a groundbreaking concept, but it did elucidate existing principles. For instance, the “SimpleButton” composable now facilitates the application of click functionality directly to the provided modifier. This strategy not only improves code clarity and resolves ambiguities for developers but also optimizes the usability of our UI components.
The “onClick” parameter excels due to its clarity and specificity. It unmistakably delineates the composable’s purpose, saving developers the trouble of delving deep into the modifier. It simplifies the development process as developers no longer need to recall which modifier component manages click behavior. By encapsulating click behavior into a parameter, developers can confidently reuse the composable, assured of its reliable performance across various use cases.
Advantages of Harmonizing Modifiers
Harmonizing Modifiers paves the way for greater versatility, improved code readability, and a superior developer experience. With clear previews and an emphasis on simplicity, developers can craft UI components that are potent and user-friendly. This approach not only elevates the developer experience but also ensures that our UI components remain adaptable to a wide range of use cases.
Exceptions to the Norm
While the new approach champions versatility, there exist instances where specific modifiers should be managed by the parent function. For instance, a component may require margin relative to the screen, a task best executed by the parent function. Acknowledging these exceptions helps maintain an equilibrium between customization and simplicity.
A Message for Designers
This change in handling modifiers is not confined to developers. Designers working on platforms like Figma, too, have a significant role to play. They can contribute significantly in upholding principles and aiding developers in their journey. For example, aspects earmarked as the responsibility of the parent modifier can also be adhered to by designers. For instance, ensuring that a component’s margins in relation to its surroundings don’t belong to the component itself. Each component is best when it is as self-sufficient as possible in its simplest form.
A collaborative approach between designers and developers ensures that the principles of harmonizing modifiers are carried through from the design stage to implementation, culminating in a smoother and more efficient workflow.
In Jetpack Compose’s evolving world, the approach to modifiers has shifted from discouraging modifications to embracing them judiciously. The secret lies in crafting composable functions that maintain a balance between customization and usability. With clear previews and a focus on simplicity, developers can create UI components that are both dynamic and user-friendly.
