[英]Flutter Row widget solve RenderFlex overflow by cutting off remaining area
[英]Renderflex overflow caused by row
我正在嘗試實現簡單的一兩行文本。 文本將有一個起始文本,然后是圖標和結束文本。由於 styles 不同,我正在使用帶有文本、圖標和文本小部件的行。 我A RenderFlex overflowed by 16 pixels on the right.
錯誤。 我將行括在靈活和擴展中,但仍然無法正常工作。 我只是希望文本在行尾下降到下一行。

您不需要對列中的行使用任何像 [Expanded, Flexible, etc] 這樣的 flex,因為行默認采用列可用的最大寬度
您收到錯誤,因為您的行子寬度大於可用的屏幕尺寸
