<\/figure>\n\n\n\nBefore proceeding with assigning actions to the “edit” and “save” buttons, it’s crucial to highlight another feature that significantly enhances the capabilities of components: component parameters. <\/p>\n\n\n\n
Components possess the ability to receive parameters from the parent component, there by allowing them to access information passed from the ListView.<\/p>\n\n\n\n
To add component parameters, follow these steps:<\/strong><\/p>\n\n\n\n\nTap on the plus icon located at the top right corner of the component interface.<\/li>\n\n\n\n Enter the desired component name that accurately describes the parameter you intend to receive.<\/li>\n\n\n\n Choose the appropriate data type for the parameter that the component will receive externally. This could be a string, integer, boolean, or another suitable data type.<\/li>\n\n\n\n Select whether the parameter is required. If a parameter is marked as required, it indicates that the component must receive this information to function correctly. This is particularly important for essential data that the component relies on to perform its tasks effectively.<\/li>\n<\/ol>\n\n\n\n <\/figure>\n\n\n\n <\/figure>\n\n\n\nIn our context, we intend to pass two parameters: an index and a text value. The text value represents the cat name, which corresponds to the value of the app state currently being viewed in the ListView. <\/p>\n\n\n\n
Meanwhile, the index denotes an integer indicating the specific position of the string within the list of strings.<\/p>\n\n\n\n
It’s important to note that we’re utilising an index because the only method for updating information in an app state list of strings is through the “update at index” feature. This feature requires the current index of the item in the list of strings that we intend to update.<\/p>\n\n\n\n
By leveraging component parameters, we can seamlessly integrate the ListView and the component, facilitating efficient communication and interaction between them. <\/p>\n\n\n\n
This ensures that the component has access to the necessary information to perform updates accurately and effectively.<\/p>\n\n\n\n <\/figure>\n\n\n\nIt’s worth noting that components can receive various types of information, ranging from document references for firebase to supabase rows, allowing for interactions with external databases. <\/p>\n\n\n\n
However, for our purposes, we solely require the index. Once we pass these parameters to the component, the Save button will have the action to update the app state at the specified index from the parameter, with the new value derived from the text input widget housed within the component. Subsequently, the save button will update the component state \u201ceditText\u201d to false. <\/p>\n\n\n\n
Note: It’s important to note that the update type for the app state is configured to “rebuild all pages.” <\/p>\n\n\n\n
This setting ensures that whenever changes are made to the app state, all pages within the application are promptly refreshed to reflect these modifications.<\/p>\n\n\n\n
When the user taps on the “edit” button, it triggers an action to update the component state named “editText” to true. This action dynamically reveals the text input and the save button, which have been configured to appear when the value of “editText” is true.<\/p>\n\n\n\n <\/figure>\n\n\n\nThe text widget and the textinput would also have some import configurations:<\/strong><\/p>\n\n\n\n <\/figure>\n\n\n\n <\/figure>\n\n\n\nNow, let’s return to our main page where the ListView is located. Tap on the listview and select the tab \u201cgenerating Children from variable\u201d then give the variable a name and pas the appstate \u201ccatNames\u201d to the listView.<\/p>\n\n\n\n <\/figure>\n\n\n\n<\/p>\n\n\n\n
Drag the previously configured component into the ListView. <\/p>\n\n\n\n <\/figure>\n\n\n\nOnce placed, we can pass the two essential values required by the component as seen below. <\/p>\n\n\n\n <\/figure>\n\n\n\n <\/figure>\n\n\n\n <\/figure>\n\n\n\nOnce these steps are completed, we can proceed to preview the application. Upon previewing, you will observe that we can seamlessly access and display information from the ListView, populated directly from the app state. Moreover, users can effortlessly edit this information at any given time.<\/p>\n\n\n\n
It’s worth noting that the same principles can be applied to editing various types of data, including documents referenced from Firebase, Supabase rows, or any other data accessible via app state, API calls, etc. <\/p>\n\n\n\n
