For loop with an if else statement Google-apps-script

I have sheet. In column A I have simbol ☑ in some cells. I need that active cell moves to cell after last cell with ☑ simbol. Now code doesn't work as I want. Please help me to change code. Thanks.

Here is my code

 function LastCellInCollA() {
  var sheet = SpreadsheetApp.getActiveSheet()
  var cell = sheet.getRange(2, 1, 1, 1);
  var i
  sheet.setCurrentCell(cell);  
  for (i = 2; i < 146; i++)
    var valuei = sheet.getRange(i, 1, 1, 1).getValues();
  {
    if (valuei = "☑️") 
    {  
      sheet.setCurrentCell(sheet.getRange(i, 1, 1, 1));
      i = i + 1;
        }
  }
}
