`If I fetch a large amount of data in initState(), will it affect my app’s performance? How should I handle a large dataset efficiently?

I am working on a Flutter application and I am concerned about the performance implications of fetching a large dataset from the database in the initState() method. Here is my current implementation:

 void initState() {
     super.initState();
     WidgetsBinding.instance!.addPostFrameCallback((_) {
     Provider.of<DealerProvider>(context, listen: false).fetchDealers();
 });
}

Problem:

fetchDealers() retrieves a large dataset from the database. I am worried that this might impact my app’s performance, causing slow load times or unresponsiveness.

Questions:

Will fetching a large dataset in initState() affect my app’s performance?
How can I handle large datasets more efficiently?
Should I limit the number of records fetched in initState() and load additional data only when users scroll down the screen?

What I Tried:

I implemented data fetching in the initState() method as shown above. My expectation was that the data would load and populate the UI once the widget was built. However, I am concerned that this approach might lead to performance issues, especially with large datasets.

I am considering implementing pagination or lazy loading to handle the data more efficiently.`
