我在這里有這些多個后期變數，它們的含義相同。
late final TextEditingController rentStatus = TextEditingController()
..addListener(() {
setState(() {});
});
late final TextEditingController rentStartInput = TextEditingController()
..addListener(() {
setState(() {});
});
late final TextEditingController rentEndInput = TextEditingController()
..addListener(() {
setState(() {});
});
late final TextEditingController renterName = TextEditingController()
..addListener(() {
setState(() {});
});
late final TextEditingController renterContact = TextEditingController()
..addListener(() {
setState(() {});
});
我想做到這一點，以便我可以在一個代碼塊中同時制作它們，而不是這些多個塊。
我試著這樣做
late final TextEditingController rentStatus, renterName, rentStartInput, rentEndInput, renterContact = TextEditingController()
..addListener(() {
setState(() {});
});
但它導致了后期初始化錯誤。
uj5u.com熱心網友回復：
您必須在昏迷示例之前初始化每個值
late final TextEditingController rentStatus = TextEditingController()
..addListener(() {
setState(() {});
}), renterName = TextEditingController()
..addListener(() {
setState(() {});
}), rentStartInput = TextEditingController()
..addListener(() {
setState(() {});
}), rentEndInput = TextEditingController()
..addListener(() {
setState(() {});
}), renterContact = TextEditingController()
..addListener(() {
setState(() {});
});
