The Get.putAsync Method
Explore how to initialize and inject asynchronous dependencies in Flutter using the Get.putAsync method from GetX. Understand how to fetch and preserve data before UI rendering, manage shared instances, and maintain app-wide persistence. This lesson includes a practical example with product data fetching and display to solidify the concepts.
We'll cover the following...
Initializing dependencies asynchronously
At times, our dependency results from an asynchronous operation, such as when using SharedPreferences (a simple key-value storage system used for persisting primitive data types in Flutter applications). We can perform the operation and initialize the dependency using the Get.putAsync method.
Get.putAsync takes the builder parameter, which is a function that, when called, initiates an asynchronous process to obtain the dependency instance. The builder function returns a Future representing this asynchronous operation, which will eventually resolve to the dependency instance once the process is complete.
As with all other methods, we retrieve the dependency using Get.find ...
