[Flutter/dart]GestureDetector event runs when page is displayed
Phenomenon
Certain icons perform certain actions when long-pressed
To achieve this, I registered the actions in GestureDetector's onLongPress event.
However, when I tried to build it, the process was executed when the icon was displayed.
Below is the source code for the relevant part.
Now, what's wrong?
return GestureDetector(
child: Container(
//・・・
),
onLongPress: onLongPress(),
);
void onLongPress(){
//actions to executed on log-press
}Cause
What you should pass is onLongPress
When passing onLongPress(), the execution result is passed, so the process is executed to obtain the result in the GestureDetector constructor.
You must pass the method instead of the execution result.
Lastly
You can easily understand it when summarized like this, but when it occurred, I didn't know what was going on and was confused lol
Actually, it was a part github copilot wrote, but I had to check it properly.
