flutter GestureDetector 點擊空白區域無反應解決辦法

在flutter中只用GestureDetector添加點擊事件，發現在空白區域點擊無效，事件不響應。解決辦法

 

GestureDetector(
     behavior: HitTestBehavior.opaque,
)

 

說明

/// How to behave during hit tests.
enum HitTestBehavior {
  /// Targets that defer to their children receive events within their bounds
  /// only if one of their children is hit by the hit test.
  deferToChild,

  /// Opaque targets can be hit by hit tests, causing them to both receive
  /// events within their bounds and prevent targets visually behind them from
  /// also receiving events.
  opaque,

  /// Translucent targets both receive events within their bounds and permit
  /// targets visually behind them to also receive events.
  translucent,
}
