7 Key Flutter App Development Tips for Efficiency

1. Always utilize const constructors

The right practice is to use const contractors for Flutter app development while you create new widgets or just use the default widgets.

2. Split up into small widgets instead of a large widget

Make sure you do not end up creating a large widget. Instead, you must split your long code into multiple small widgets. It will help avoid the heavy build function associated with a large widget.

3. Employ Lazy Loading

Flutter developers should implement lazy loading with callbacks so some data starts loading at the same instant it is called. Lazy loading will work efficiently when there are large Lists required to be loaded.

4. The use of itemExtent is crucial for long lists

In case you are working on very long lists of data elements, you might wish to make significant scroll jumps in the list. And so, you can simply use ItemExtent in the ListView, this will allow you to make controlled jumps in the scrolling.

5. Use If Null Operator (??)

?? (Null Operator) is used to check if the value of an element is null. So if it is null the operator will return the value after ‘??’. However, in the case it has a value, it will return that value.

6. Start using Spacer Widget

Developers use Container and define them certain height/width to establish a responsive space between widgets. However, this just looks good on a few screens and may overlap in smaller screen sizes.

7. No Text Style redefining hassle

One hassle was to define the text style every time some customization was required in the Text. Furthermore, this became hectic in the case of multiple themes (Full Black Theme, Light Theme, etc.).
