About six months ago, I embarked on my FlutterFlow journey. Two months into this journey, I took on a significant project requiring efficient handling of multiple data tables. Here’s how I optimized data querying and search functionality in FlutterFlow:
1. Initialization and State Management: I used two main page state variables to manage the data:
exampleList: This document-type variable toggles withisListand holds the queried data.isShowFullList: A boolean that controls whether to display the full list or just the filtered results based on the search criteria.
2. Data Query and Initial Display: On page load:
I query the required collection and update
exampleListwith this data.In the DataTable widget, I set the value to
exampleListto display the initial full dataset.
3. Implementing Search Functionality: For dynamic searching, I utilize the onChange event of a text field:
Check if the text field is empty: If true, set
isShowFullListto true (showing the full list). If not, set it to false (indicating a filtered view).Apply a simple search: Use the initial query output and filter it based on the text field's value.
4. Conditional Display Logic: Based on the state of isShowFullList:
If true, I reset
exampleListto the original data from the onLoad page query (full list).If false, I update
exampleListto display only the results filtered by the search criteria.
This approach ensures that the table starts populated with data and allows for effective searching. If anyone has insights on optimizing this further or finds this method useful, I’d love to hear your thoughts! 🍻
